300 Blackout boolet

[fivegunner]

I just put togather a 300 Blackout, has there been a GB mold here, anybody have a good idea as to what would be a good boolet for the Blackout??:-D

[A pause for the COZ]

If your looking for supersonic shooting try the LEE C312-155-2R. This is a very very good boolit in 300 Black Out.

[Wayne S]

Check NOE's web site, they masy still have a few 311-247 molds, mine drops at at about 244 Gn.

[nhrifle]

I can't speak for the NOE boolit mentioned above as I don't have that mould yet, but the Lee 312-155 works great in mine.

[fivegunner]

anybody here would like a copy of Lee`s c312155r2 made by Mihec??. I sure would. could someone start the ball rolling??.:-D

[Oreo]

I'll honcho it if you guys like. Can someone post a blueprint? I'll need to contact Miha and get permission before I take it active.

[Jupiter7]

Oreo, You can count me in on the buy. I think a 3-4 cavity 150gr-ish .311-.312 in that design would gain interest quickly. Maybe a.314 option for those "other" 30's.

I'm in. As many cavities as they will make. It'd be nice to have a PB and GC option as well.

[Oreo]

I need a blueprint first. Our journey must start with a blueprint.

If one does not exist then I can draw one but we as a group will need to do some research on what makes a good design for this cartridge. After I do a sketch and revise it several times based on your feedback we'll have something decent to go active with.

[fivegunner]

That sounds great! now all we need is a Blueprint. I am not much help there. maybe someone will jump in with a Blueprint , I sure hope so. :Fire:

[Oreo]

If we don't have a blueprint just post some pictures to get me started. Give me an idea ofvehat you guys want and I'll start sketching.

[MT Chambers]

My .300 is a boltgun and really likes #311332 and RL-7

[27judge]

The RCBS 180 sil . bullet has worked very well for me with GC and 1680 it shoots under a inch at 50 yards and cycles the action every time tka KEN

[Oreo]

What about the 30sil boolit that 45 2.1 ran a Mihec gb for a few months ago? If there's something already that works well there's no need to reinvent the wheel.

[Jupiter7]

Oreo, send me a pm, I'll send you some as cast samples of the lee 312-155, if that'll help.

[A pause for the COZ]

I am in!!!!

This be the boolit right here.

[Jupiter7]

What about something like this. Chop above bottom drive band and make bottom lube groove into gas check shank. Please forgive my ignorance if this isn't feasible, bullet design isn't my forte.

Edit to add, 4 cavity with a small HP on one cavity would cover it for me. That or add a small flat point.

[doctorggg]

I'd be in for a 312-155-2R.

[shangrila]

I'd like to see something like this: RCBS 2-Cavity Bullet Mold 7.62mm-130-SPL 7.62 mm , 30 Caliber (309 Diameter) 130 Grain Spitzer Point Gas Check, in a 6 cav. AL mold with PB as an option.

[fivegunner]

I would be happy with a 6 cavity mold cut in a 4 cavity block, copy of the Lee 312155r2 from MiHec.:Fire::-D

[Oreo]

Ok, lets back up a couple steps further. Supersonic or subsonic? Lets start there.

I see a number of you asking for the 312-155 as a supersonic but a lot of you have ideas all over the map. I want as many people on the same page as possible before we continue.

[Jupiter7]

I thought we were on the path of something similar to the lee 312-155 with optimal feeding and mag fit being paramount, supersonic. Of course cut by a master mold maker in more than 2 cavities.

[shangrila]

A 4 to 6 cavity, supersonic with either PB or GC option. Biggest issue would be feed and function with the AR platform. Just my .02.

[Smoke4320]

yes to the above ..
lot of people like the lee 312-155 for a reason... it works.. in Blackout, 7.62x39 and 308..
Just need more cavitys to speed up the making process

[fivegunner]

My interest is a good accrate boolit I can shoot out of my AR. 300Blackout, I have heard the Lee 312155r2 is a good one in the blackout. I just would like more cavity`s, :Fire:

[prsman23]

What he said ^

[Fishman]

JT of heavymetal moulds has started a poll for the next boolit design in his production. Stop in and vote for my request for the Lee .312-155. His moulds are phenomenal.

[Oreo]

It looks like enough of you want the 312-155. One person has been kind enough to put some samples in the mail to me. Give it a week for me to get the samples and start sketching.

[doctorggg]

+1 on that

[Fishman]

This design seems to be a hit over at the HeavyMetal discussion on the next mould design. I sure didn't expect it to take off like it has but there are a lot of people on that thread asking for a copy of the Lee boolit and JT appears to be very interested as well. Oreo, you might not have to do any of this work you have brought upon yourself :) but I am grateful that you are willing. We shall see what JT decides to do.

[A pause for the COZ]

Please please please please please please please please :bigsmyl2:

[fivegunner]

If we went for a copy of the Lee 3121552r what would you all want to be the as cast dia. ?? :D[smilie=2:

[Jupiter7]

.312, be nice if it'd actually pour out at 155grs vs. the 160grs I get with every alloy.

[Oreo]

.312, be nice if it'd actually pour out at 155grs vs. the 160grs I get with every alloy.

These are the kinds of details we need to discuss. I can draw the blueprint to be any diameter and weight spec. you guys want. However, things like center of mass, center of pressure, ballistic coefficient, etc. all come along for the ride so in the end the right set of compromises need to be made for the boolit to be capable of the best performance. You guys don't have to worry about those calculations since that will be my job as part of drafting the blueprint but it will be necessary for you guys to decide the basic design parameters in advance.

[fivegunner]

Yes sir. we need more input on this GB, I know theres a few people out there that own the 300 Blackout, if they could just post what they think would be a good boolit to go for. I hope we can make this happen.:D:lovebooli

[Moonie]

I also use the Lee 312 155gr Lee boolit in the 2 300AAC BO uppers one of my sons and I own. This is a great boolit for the 300, 7.62x39, 308 and I also use it in light loads in 30-06 for my 14 year old daughter. I'd absolutely go for a 4-6 cavity version of this mold.

It feeds perfectly in every 300 BO we have tried it in. I'd want it in .312 or slightly larger.

[Oreo]

You guys think .314" would do it?

[A pause for the COZ]

.314 would be a bit big, I think. I size mine to .310 so .311 or .312 would be best for me. A PB option would be nice. But I think I would order a 2nd mold for that.
I havent had the greatest luck getting PB bullets to fly. Not saying if a .314 option was there. That might be a good one for my 303 or my Mosin. Crud looks like I would spend 300 bucks just on this mold.

[Jupiter7]

Agreed, .314 would be fine for those "other" .30's. For the .308's, .312 is perfect. I personally size .309. I'd be afraid sizing .314 to .309 would lose a fair amount of lube groove and possibly sizing down of the ogive. In theory, increasing bearing surfaces and decreasing lube capacity. I tumble lube but for others with lube/sizers a definite downside, especially when moving this bullet to full rifle calibers like 06'.

[FLYCUTTER]

My vote is with the rest of the members, a.312 weighing in at 155 gr.GC.

[Oreo]

I like to keep options to a minimum when possible because I think making life easier for Miha helps get a gb to producion sooner. But, we could do a size option, .312" and .314" if there are enough orders to justify it.

[Moonie]

.312, as I size to .309, .310 and .312 for different rifles.

[JTknives]

hey guys, I was on the forum and felt my ears burning. So you guys want a black out mold. I have a tweaked design of the lee but if you guys want a straight up copy I would be more then happy to do it. I will start a discussion thread where we can kick around ideas. I will post my drawing that's my best guess on the lee. But ya we are ready to go on any design you want as long as we got the people to justify a $300 tool. We have very quick turn around, right now we are running 500 mold blanks that will be waiting for cavity's. So that being said I'm guessing 2 week turn around time.

[xacex]

I like the lee boolit, but I dream of having it with a hollow-point. I know, I cant have everything. I hope to see the 311410 soon from MiHec.

[fivegunner]

that sounds great! could you tell us a littel about you, and your molds and your copy of the Lee 3121552r???:D

[Patrick L]

I would be in for a multi cavity copy of the Lee boolit at .312. I would like a PB option.

[HATCH]

I want a 300bo mold for my master caster.

[Smoke4320]

"lot of people like the lee 312-155 for a reason... it works.. in Blackout, 7.62x39 and 308..
Just need more cavitys to speed up the making process "

Again I vote for this ...4, 5 or 6 cavity

[JTknives]

OK guys I started a thread on this project, check it out

[Oreo]

How many people here still want a Mihec version of this? I just got samples in the mail from Jupiter7 but I'm not going to waste the considerable time and effort drawing this up if there aren't enough people willing to see it through.

[xacex]

I would like a MiHec version. One thing is he can do a H/P in it as well as the spire point. Draw one up with some H/P's like the 311410 group buy that is being cut.

[Jupiter7]

No offense to JT, I have one of his 225-62 molds, it's great. But I'd like to see where we can get on the miha mold also. And a HP option on one cavity would be great. I think that the miha mold will garner more interest by name alone. A straight 4 hole copy, no improvement needed.

[fivegunner]

I would like a Mihec mold. no offense to JT. :lovebooli

[JTknives]

no offense taken, we are still moving ahead with our 312-155 and hope to have molds ready to ship in a month give or take a titch. I got the idea to cut this boolit from a bunch of people on my area in the forum. A lot of people have been asking me to make it so that's why i posted here that i was making it. Mihec makes a good mold, i have one of his molds and love it. It just takes FOR EVER to get them.

[shangrila]

I'd like a 4 to 6 cav HP version from Mihec with all the pins along with a 312-155 from JT. I like options. :)

[fivegunner]

yes ,your right it takes a long time to get a mold from Mihec, I have over 20 now great molds. I am going to buy one of yours and give it a shot, as I am only looking for a mold for my AAC Blackout, that will shoot well , and cast a lot of boolits fast!!:Fire:
