Here is a picture of the basic design out of my Lyman's Cast Bullet Handbook:

http://i1102.photobucket.com/albums/g443/system_admin/311440.jpg

And here is the modified design by 45 2.1 that the Group Buy is asking Miha to make:

http://castboolits.gunloads.com/attachment.php?attachmentid=36638&d=1318679628

Miha is amenable. He said start a list and send him the link.

We'll be keeping the list here. These will be Cramer-type moulds, with captive hollowpointing pins that, erm, well, here's a picture of one (A different mould than this buy is buying. It's a handy picture to demonstrate the Cramer-type hollowpointing concept.):

http://www.mp-molds.com/images/cramer_45_render_cr.jpg

And if you go here, there's a video of someone casting with one:

http://www.mp-molds.com/index.php?nShow=27

The design details I've forwarded to Miha are:

"American" diameters are 0.301" bore-riding nose and 0.312" driving bands.

"Standard" diameters are 0.303" bore riding nose and 0.314" driving bands.

If you all can conceive of changes or additions that ought to be made, this buy is still in the Discussion phase.

I've asked the administrators to close the original discussion since the buy has split into two buys, but here is that thread for reference:

http://castboolits.gunloads.com/showthread.php?t=126727

Notice:
I anticipate we'll be going Active soon. We're waiting on prices, block size availability (2C/4C), and final confirmation of the 45 2.1 design.

Will this mold be made in brass? Is the design of 2 and four cavity what is available on this GB? tia barry

bronte454
10-01-2011, 09:25 PM
My understanding is this is for a Mihec brass mold in the cramer style hollow point mold . 2- 4 cavity is still open for discussion . I am happy to go along with either 2 or 4 cavity and I notice on the list I did not specify at the time but I would like the American dimensions . Typically with Mihec cramer molds you can flip the pins over and cast the standard nose profile w/o the hollow point . Absolutely piece of art work . The 5 molds I have from Miha with at least 3 more with my name on them .

I think these will be brass moulds. I don't know if aluminum Cramer/RG type moulds are made. My first guess is that hot aluminum is too soft and those side pins running back and forth through it would ruin the mould in a hurry. Maybe this can be solved by putting steel sleeves in the block, for the side pins to slide through. I don't know. By the time the extra parts are made and fitted, aluminum might be more expensive than brass. I think they are going to be made out of brass.

As for the number of cavities, that may be an optional option, or it may be solved democratically. After Miha gets back about the overall feasibility of the project, I'm going to run the list of potential options past him. That would be:

Materials of construction (aluminum or brass)
Number of cavities (all moulds 2C, all moulds 4C, buyer's choice, 1C?)
Diameter (American, Standard, one diameter per mould, or mixed diameters in one block?)
Plain base or gas checked (all the same or mixed bases in one block?)
Pins (round, pentagonal, blank)

Have I missed anything?

NOE calls their hollow point molds RG4 they are a completely different style of making hollow points. Miha makes the Cramer style hollow point molds after the original style Cramer of yrs gone by .

10-02-2011, 07:26 AM
HenryC460,

RG hp = Rube Goldberg, the hp method NOE uses on their aluminium molds..

Cramer hp = Cramer, like Mihec makes (photo above) and the original name that Lyman used IIRC.

Two different designs to come up with a HP bullet..

edit: bronte454 I see you beat me to it...:)

HenryC460
10-02-2011, 10:55 AM
Thanks for straightening that out for me.

I suppose since our manufacturer is Miha, these are Cramer-type moulds.

Ah, here's an RG4:

No problem, understood. As has already been mentioned, Miha makes Brass Cramer-type moulds.

Miha Brass 2 Cavity Cramer HP = Perfect. Now I just have to decide between plain based or gas checked. (I have to decide if I want to go the PlainBased route to try Pat's PlainBase Gas Checking method). Choices choices. :bigsmyl2:

Thanks Henry! You have finally listed the mold I have wanted all through the discussion IE: brass, Cramer, gas check, reversable pins. IMHO, brass cramer molds can't be beat. Please add that I want the "American" 301/312. This one should go active soon.

Could this be made heavier? It is going to be fairly light as a hollowpoint. Since this is a hunting bullet it would be nice if it had a little more but not excessive weight. 165 gr from WW alloy would be nice! If we could make it 175 grains I would not see how I could refuse another damn 30 caliber mold. I wonder how much another drive band would bring it up?

Will there be a choice of pin diameter?

This one has me thinking, but it will have to be a little heavier for me.

I think diameter options are not a problem. I'm going to ask Miha about weight options, like adding an extra driving band like you said.

I can't speak for others, but the fairly light weight in HP form is what attracted me to this mould. :)

bronte454
10-12-2011, 07:44 PM
I agree with Dannix I like the weight the way it is . With such a small hole it isn't gonna loose much weight I've got 170 180 210. I bet with H.P. It'll come in around 140-145. Just my .02 cents

HenryC460
10-14-2011, 04:35 AM
I've asked Miha anyhow, about the feasibility of (optionally) adding a driving band to (as an option) make a heavier boolit. My (limited) understanding is that more than one cherry is used to make a mould, so it may be possible (or a ridiculous misunderstanding on my part) to cut part of the cavity, move the "driving band" cherry vertically a bit, and cut some more, resulting in a longer boolit with more lube grooves.

I'll let you all know when I hear back.

kbstenberg
10-14-2011, 05:29 AM
Why doesn't the bullet next to the mold look like the one we are interested in. LOL
Depending on the finished inf. (price, weight) I would want an American .301/.312 large hollowpoint pin, GC, 2 cavity. 1 pair of extra pins

They are basically a drill bit with the mold blocks in a jig that is clamped tighter and tighter around the spinning cherry until the block is fully closed then the jig is opened up. Lyman used to 'custom' cut usually lighter weight boolit designs from popular mold designs for folks by eliminating a portion of the shank. This also removes the gas check shank on the base...which I assume everyone wants? It's not a big deal to me. I have fooled with this boolit before and did not have much luck. I always thought it would be better, at least in my rifles if it was another 20 grains heavier. To be honest, I have a love hate relationship with the bore riders.

45 2.1
10-14-2011, 05:59 PM
I've fooled around with three iterations of this basic design. I would suggest thicker driving bands and that they be manipulated to fit the 30-30, 308 and 30-06. With the big flat nose, this design is a hammer on game and doesn't seem to need any more weight to make it effective. Miha cannot change the relative diameters due to gas-check shank fit..... although it would be easy if a PB version were wanted (or a shortened boolit without the GC shank attached)...........make sure of the dimensions wanted. If you want a complete drawing suitable to machine a cherry (which the one shown is not) to send MiHec, I could provide such.

Hi 45 2.1

I'd sure like to look at the drawings and forward them to Miha.

Is the difference between 30-30, 308, and 30-06 the position of the crimp groove, to get the right OAL for the loaded cartridge? What's the groove forward of the crimp groove?

bronte454
10-15-2011, 08:13 AM

I forward drawings to Miha via AutoCad and can't be opened on a computer unless you have the drawing program. We have had a working relationship since he started doing this.

Is the difference between 30-30, 308, and 30-06 the position of the crimp groove No, thats basically for the 30-30., to get the right OAL for the loaded cartridge? The body length is suitable for all three cartridges when seated to the base of the neck in each. The crimp groove becomes a lube groove in the 308 and 30-06. What's the groove forward of the crimp groove? Thats refered to as a dirt groove.

The original Lyman version dictated the overal and body lengths. The basic difference is the band and groove arrangement. This ain't a 300 yard target boolit since its BC is fairly low, but it does knock game game very well.

If this one goes, the nose portion dimensions need to be discussed. The modified version was meant to fill the throats of 308 and 30-06 rifles fully (and it does) along with being very good in the loose chambered and throated Win 94s. It does not chamber. The nose engraves along its length and can be forced in the Marlins as it is. A 0.301" at the meplat radius and about 0.303" at the dirt groove would probably fit correctly.

I know with some of the other group buys There's as many as three different options for the hollow point pins the 454640 group buy for example has a large size a medium round size and the penta and a flat set specifically for pouring solid if the individual is not comfortable with turning the hollow point pin over (I.E. Not to damage the pin poking out the bottom). I feel comfortable that Miha can accommodate us . Personally I think a large round pin would be useful for low an slow bunny loads and then a smaller deeper round pin for higher velocity loads. The extra pins sets have been running 16.00. Per extra set .

The reason I asked is, I have the .35 cal. FN bullet pictured below which is simular to the GB bullet Similar isn't the same as......... someone else did those and I have no idea if they fitted it properly so it would feed and fit correctly. Seating properly is a nose engrave, base of neck arrangement so that it will extract and not pull the boolit. This one does that in the firearms listed..... and has been doing so for the last three years. and it doesn't feed in short actioned Remingtons, Ruger 77, Marlin XS7 and 3 Mauser actions I tried it in..

Currently its being tried out in the Ruger Gunsite. Seating to an OAL of 2.50" gets a nose engrave, gas check at the case neck base and excellent feeding and extraction. 30-06 firearms do likewise when seated correctly for that cartridge.

Yes, I think we go Active when the pins and a finalized drawing are settled. My understanding is that 45 2.1 is working with Miha directly to sort out those details.

Pins in a cramer need a basic 15 degree taper per side to release......... therefore the HP isn't going to be to deep (not that it matters much with the velocities possible in a rifle cartridge). Another question bears some discussion Henry........... whether or not this should be fitted to include the Marlin 30-30s. The nose needs to be smaller somewhat for that to happen. Two diameters will require some fun machining for the gas check shank with one cherry........ or two cherries for the two diameters normally done for GC molds. This design could be produced for the normal thirties up through thirty-five caliber with one cherry and that fun machining I mentioned..........But MiHec may not want to do that after the first run. Think about that also. MiHec doesn't design the boolit............just makes it to spec where it works properly. You'll probably have a choice of a blank pin for a normal flat nose and a HP pin. Answer these questions and we can go on.

The the somewhat smaller nose needed to be kosher with Marlins impairs implementation or performance in Winchester 30-30 and 308/30-06, I'd be inclined against it, but that's just my 2 cents.

...Another question bears some discussion Henry........... whether or not this should be fitted to include the Marlin 30-30s. The nose needs to be smaller somewhat for that to happen...

I've got a question about that. Maybe two.

From what I understand about the manufacturing process, a single cherry can cut plain base cavities in different diameters. Thus, if everybody wanted plain base cavities, the same cherry could cut:

an "American" 0.301" bore-riding nose with 0.312" driving bands or

a "Standard" 0.303" bore riding nose with 0.314" driving bands.

And if everybody wanted gas checks, the shanks would be 0.002" different between the two, and that's the problem, I think.

So there is a second, shank cherry, and that's used to cut the gas check shanks, and that's a separate machining step and machine setup and exploratory scrap making exercise.

So here is a proposal about Marlins, for discussion purposes.

A boolit with 0.312" driving bands seems generously fat to me. It will probably get sized down to 0.310 or 0.309. What if a third set of diameters, "Marlin" diameters, were made:

0.300" nose and 0.311" driving bands or

0.299" nose and 0.310" driving bands???

At 0.300" or 0.299", would the nose provide enough bore contact to do its bore-riding thing?

Would these reduced nose diameters allow this design to function in Marlin chambers?

Would a pure lead boolit cast in an existing mould come out about that small and provide a test piece to find out?

If it did work in Marlin chambers with a 0.300" nose and 0.311" driving bands, would the same boolit be as good as the "American" design in other chambers?

I'm no expert on this, but is the extra 0.001" of nose diameter above bore diameter something that is desirable?

I don't know yet. As a rough guideline, you could look at the prices on some of Miha's current group buys. Design complexity, raw material costs and currency exchange rates could lead to some differences.

For what it's worth, a Marlin 30-30 is on my wish list but not currently on my gun rack. If I need to shoot this boolit in that gun, I can probably rent a chamber reamer or my gunsmith can, and that will fix the throat problem.

Marlin incompatibility is not a deal killer here.

I've been following this, but not quite fully committed to jump on it yet, so my opinion is of dubious value.
That said, I like the Mod design but wouldn't be interested if it was adapted to the Marlin.

HenryC460

I propose that we call Marlin compatibility a non-issue and go with the 45 2.1 modified design in nominal "Standard" and "American" sizes.

Any objections to that? All involved have until Monday morning (American Eastern Standard Time) or forever hold your peace.

If we can settle on hollow point pin design (maximum opening that has a 15 degree taper?), number of cavities (unless Miha wants to offer both 2C and 4C), and a price; we should make this an Active buy.

I agree wholeheartedly! :Fire:

My Winchester '94 will work just fine with the "American" dimensions listed above; and I'm sure I can find something in the safe that will like the "standard" dimension boolit.

I'm stepping out of this one in favour of the NOE 311440.
Realized I will probably have issues cycling this in my Marlin 336...
Sorry for any trouble caused.

You know the more I think about it the more I am glad I got in on this buy. I cast a bunch of original 311440 bullets the other day from a single cavity mold. For the life of me I can't get the top lube groove to fill. After sitting there and mulling over it for a while decided this design is exactly what is needed. I can't wait to get it.

I have updated the list and PM'd Mia asking about finalization of the 45 2.1 design, block size (2 or 4 cavities), and the prices. I will let you know when we have answers.

I'm eager for this buy to become Active, as you can imagine, but I really want to be able to tell people exactly what they are getting and how much it will cost before I ask them to commit.

Thanks for hanging in there.

I've got answers.

Miha can do both 2-cavity ($90 plus shipping) and 4-cavity ($125 plus shipping), but he prefers to do one or the other. Production is simpler and faster with a single block size.

I think we are going with the 45 2.1 design, and I've re-asked to clarify that.

We will be Active shortly.

For only $35 more, I'd vote 4-cavity.

Seems like a good value to go 4-cav at that price differential, even though this likely won't be a 'primary' mould for me. But I won't be too grieved if the majority chooses the 2-cavity route. :cbpour:

I'm just writing to let you all know that this thread is going to be locked, and an Active thread is going up.

Here is a link to the new Active thread:

http://castboolits.gunloads.com/showthread.php?t=142028

I plan to migrate the list over as-is and edit it up or down and for block size and available diameters as needed.
