Looking for a heavy 9mm boolit

[20:1]

I am currently using the mp 135 rnfp BB, and it is an all-rounder
so what I'm looking for is not much beyond what I have already tried, it is 12 grains heavier than what I am using
but it would be a great saving of powder
What you say about the boolit base is very true, I still wonder if a beaver or normal base is more accurate
I think the flat base is more accurate.

If you're already using a RN design you might consider it. Some 38/357 designs have been used successfully in 9mm as well. I mentioned 358156, but I've had success with 358311 Lyman (158 gr RN) and others. I see Miha is out of the RCBS 147 design now but does have non-grooved 147 RN designs left. It appears that he's getting hit pretty hard on his current sale. NOE doesn't show much, the afore mentioned 155 gr ELCO design is available in some configurations. After that it appears to be the usual Lee, Lyman, and some limited RCBS. Or you can go the custom route.

yes, but round nose
It's not that difficult to handle for a semi-auto pistol.

In this pic you can see some of the bullets both coated with PC and Hi Tek. The rounds on the left are loaded longer for the revolver and the round on the right is loaded to length for my autos.

I really wish I had actual physical contact with other reloaders rather than just online like this. As it happens. with NO idea what I was actually doing, I loaded what turns out to be 800 rounds of perfectly good 9mm revolver ammunition. It won't fit in a Glock but thats actually OK at this point.

I am now curious as to why someone would intentionally load it longer so it would only work in a revolver. It would be lower pressure I suppose - also hit the rifling sooner. What is the actual advantage of doing this?

[20:1]

Relatively new to this - one of the things I have been wondering is why there is no refrence in any manual I have seen to where the bottom of the bullet should be. I see overall length, powder measurements and bullet weights - but the design of the bullet could, even with the same weight and overall length, seriously affect how much space is in the case after it is seated. Looking at this picture I wonder how you could get enough powder in the case for it to even work. Yet clearly it does.

I have the Lee 356-125-2R and once powdercoated and seated to a normal length it will not chamber. People have told me to seat it deeper but I have been hesitant to do so - but its a much lighter bullet and would not have to go as deep as what I see here.

I loaded a lot with 3.0 of 700x as I'm not looking for high power. Seems in the future I should seat them deeper until they pass that Lee ammo checking tool I just got. What I already made up seems to be OK in my Uberti revolver so no loss - just education.

Look into a sized, empty 9mm case and you'll see how the inner case wall starts out straight, and then abruptly starts to taper inward. You should not seat any bullet any deeper than the very start of that taper. Measure the distance between the open case mouth and that point. That is how deep you can seat a flat base bullet in that case. The bullet base will start bulging the case at that point, and it's best to be just slightly above it. If you're using a bevel based bullet design, the stopping point is the point the beveled base meets the straight portion of the bullet shank. Do not seat the bullet below the origin of the cases inner taper.

From that point you can seat a bullet in an unprimed case to the depth you've already determined and check your overall length against published OAL length spec, and/or by seating this dummy round first in the magazine to make certain the bullet isn't too long for your magazine, then you can insert the dummy round into the pistols chamber to see how well the assembled cartridge will chamber. This can be done either by removing the barrel from the pistol and dropping the dummy round into the chamber and watching how it fits. This is most often referred to as a "plunk" test. The dummy should seat fully under it's own weight. Then reassemble the gun and hand cycle the dummy round into the chamber through the magazine. Do not, under any circumstances attempt this in a room with loaded ammunition in it, and the pistol must be handled as if it it loaded with real ammo, and is ready to fire. It would almost be better to do this test at the range with the pistol pointed down range for safetys sake. If everything lines up okay, you should be ready to load up a few test rounds for the range with your selected starting load. Be sure to record the OAL you determined so you never have to do this again with this combination.

I don't know how many home loaded 9mm rounds I've seen with the base of the case bulged out from the bullet being seated too deeply. It's even harder to identify when most carbide 9mm sizing dies squeeze the case down way too far to begin with. I hope I wasn't too naggy with all the safety talk, but we all need to be totally careful when doing things like this.

He's probably using one of the 9mm competition revolvers and this is a dedicated load for it. I used to load 215 gr cast bullets in 38 Spl cases for bowling pin competition. Those were a mite unusual to look at too.

If you can live with a 135 gr design the 9mm Ranch Dog bullet is available through Arsenal, and I think you can get it in a 5 cavity. NOE lists the 135 Ranch Dog but has never had any available for the past few years. I use the 9mm Ranch Dog in almost everything. My mould is a plain base, cut for conventional lubing, but PCs well and is very accurate. http://arsenalmolds.com/bullet-molds...it=99999999999

I'm also using this Ranch Dog bullet from Arsenal. I have it at 1.060" OAL to fit into my HK P30. My mold is a 4 cavity brass. I am powder coating this bullet. 4.0 gr Win244 gives me an average of 1034 fps.

[pipehand]

This is why I want to use a heavy boolit, because the savings in powder are substantial!

Thanks!!

I remember when we were first getting accusromed to the non-availability of wheelweights and how some were using the lightest boolits possible to save on lead. Now we are seeing powder at double what it wasnot that long ago, and some optimize their miniscule powder supply with bigger lead. Hard to keep up with the latest trends.

I recently got the Lee 147 mold & got it casting good bullets. I like the bullet, shoots well at 9 minor or +p. I coat mine but a good choice in an affordable mold.

A valuable lesson there. Never load a bunch of anything you havent tested.

[nueces5]

Well, thanks for the help, I have finally bought the 147 grain MP, God willing it will arrive next week in my country.
We will wait until it is a little less hot to use it, 89 F here, with a lot of humidity

Yes, 20:1 you are correct. These are loaded for a S&W 929 which is an 8 shot 9mm revolver that uses moon clips. Not that these loads are at the top of the pressure limits but anytime you can seat bullets out further in the case means you increase the internal case volume which will decrease the pressure of the round when firing. Also in this case since the revolver is an N framed revolver (same as the .44 mag) the cylinder has a bunch more leade for the bullet to travel through before it hits the forcing cone and the rifling so I seat it out as much as I can as long as the loaded moon clip still falls in and seats completely without any interference.

The gun in the middle is the 929. It has a titanium cylinder and is tuned to a 6 Lb. double action only trigger pull. This shoots really well with the MP mould bullets along with most others I have tried.


The one on the top is a "Model of 1988" S&W 625 5" bbl. and the one on the bottom is one of the original S&W 627 5" bbl. 8 shot .357 mag revolvers.

That actually feeds ?

Tell me it does....

It feeds at 1.125 oal.

Congrats,that will be a nice Christmas present.

It's a good practise to do a few pre-heat cycles for a new brass mold. You build some patina that way and it prevents the risk for smearing lead.

[dr_rick]

I purchased the Lee 147 Grain bullet two cavity mold and I have not had any issues. I ran it through the chronograph, and it performs like a 45 ACP in velocity characteristics. Seems to have less felt recoil than my 124 grain bullets. Cycles and feeds well in any of my semi-automatic firearms.

Thanks!
but I bought aluminium 8 cavs!!
I have to find a thread that tells how to clean it before using it.

[mehavey]

how to clean it before using it.

Toothbrush
Coupla drops liquid dish soap
Hot tap water

First batch, only to test the mould and different loads
