I need to talk to a reloader with depth

[J.Boyette]

Here it is.

.308win

I want a slow down range bullet for hunting.

I want it with benchrest accurate levels from 0-200yds

That will work in 1-10, 1-11, 1-12 twist barrels.

It needs to cycle a AR-10, and work in a bolt gun as well.

I want the bullet to deform so much it will not be a over penetrating issue past 10yds or so.

Can this be loaded?

If so let me know and I will start on it ASAP. I know someone here has done it.

BTW, thanks alot!!!

John

Wow, that's tall order! No overpenetrating tissue beyond 10 yards? What are you hunting just out of curiosity?

To have it function flawlessly, then load them to spec 2.800" and FL resize everytime. That way they will chamber in both bolt and gas gun. Don't know of any projo that won't overpenetrate at 10yards, unless you are shooting at a dinosaur. LOL

Re: I need to talk to a reloader with depth

Brother,

I posted I want, not that it could be done

I should re-type that, 10yds after exit of the target.

I think with a Nosler 125grn Ballistic tip flying at 1800-2000fps might do it.

But I do not know that for a fact, or what if we looked at the Hornady 30 Cal .308 110 gr V-MAX™ flying slow or SUPER fast?

PM if you want more details.

Sorry I couldn't be more helpful but general dictum shows that heavy bullet (HP preferably) and slow speed will mitigate against overpenetration usually. Good luck

Re: I need to talk to a reloader with depth

Look into the Lapua mega bullet. I don't know about "benchrest accurate" since I don't shoot benchrest, but they shoot as well as an Amax out of my rig to 400yrds or more. Without knowing what game you are after, I can't comment on penetration issues.

Guys,

your help is greatly appreciated.

Re: I need to talk to a reloader with depth

The Vmax at high speed would certainly be accurate. you wouldn't over penetrate, but will you penetrate enough to get the job done? those things are like grenades the way they disintegrate on impact. tested a few on water jugs a few years ago, the largest single piece recovered was just over 6gr.

Re: I need to talk to a reloader with depth

Yes, it can mostly be done. One of the easiest ways to do this is with a gas checked, cast lead bullet and to tailor the load and lead hardness.

Shoot me a PM, I might be able to help you out in a short time frame.

John,

To fit all your criteria there is only one bullet currently made that I know of: Barnes MPG. Made in 140 grain weight for the 308.

Here's the write up that accompanies this bullet:

<span style="font-weight: bold">"Barnes offers bullets featuring Multi-Purpose Green (MPG™) technology developed for military and law enforcement applications. MPG bullets feature a highly frangible, powdered-metal copper-tin core inside a guilding metal jacket.

Unlike frangible bullets lacking a protective jacket, MPG bullets remain intact under the rigors of handling, feeding and firing. This eliminates the primary cause of jammed actions and plugged barrels often experienced when firing frangible ammunition.

The 55-grain 5.56mm (.224) MPG bullet is designed for M4, HK416 and AR-15 type autoloaders and other firearms with rifling twist rates of 1:9” or faster. A 140-grain 7.62mm (.308) version is available for AR-10, SR-25, M40 (Remington 700) and M14 rifles with 1:12” or faster rifling twists. These open-tip bullets remain intact at ultra-high velocities and extreme rates of spin. On impact, they deliver explosive fragmentation.

Barnes’ Multi-Purpose Green bullets are exceptionally accurate. They’re ideal for shooting steel targets, competition, plinking, varmint hunting and home defense. “Green” is military shorthand for “lead-free”—a requirement in military and LE practice environments."</span>

This bullet should disintegrate inside the target, and should have no over penetration. Should be ideal for a lung shot out to 200 yds.

Re: I need to talk to a reloader with depth

John, I am just brainstorming here, but I am not sure you can get a bullet as light as 125 gr to shoot at 2000 fps. I think you would be way below minimum load, and might run a chance of a squib. Again, I don't have experience with working a load up this slow, so maybe someone else can chime in here.

"I posted I want, not that it could be done"

Sorry sarge, but what you want - perhaps what we all might want - isn't from cartridge ballistics, it would have to be magic.

Re: I need to talk to a reloader with depth

Fuzz,

Roger that.

Shooters,

What I want is a round that from with in 0-200yds would not over penetrate a human head shot.

I just got done teaching at a Sniper Conference and one set of facts stood out to me. After teaching, it got my mind rolling.

ASA Sniper Utilization Survey report 2005.

http://www.americansniper.org/new_page_12.htm

In the national totals of sniper shots

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">
Total Sniper Shootings 219
total Fatal Shots 172
Rounds stayed in target <span style="font-weight: bold">22</span>
Head 104
Body 104
Arm 7
Leg 2</div></div>

Thats a total of 150 over penetration shots. I think with the types of bullets on the market now, there is the golden pill. Keep in mind this is a non-barricade round. Just a basic tissue-cloth round.

Re: I need to talk to a reloader with depth

It could be done with a simple ammo change in bolt actions and a minor rifle update with AR10's.

The bolt action can be done with frangible bullets loaded in reduced capacity cases or regular cases with an exceedingly slow powder with a very heavy charge (Lots of super slow powder and you're get good ignition and low MV's) Something like H1000 filled all the way up in the case with a 140gr MR(something) like was posted above.

I'm sure you can do it with testing and development.

The AR10's could be made to cycle with a gas block change to a tuneable/adjustable gas block with the same ammo. Using a slow powder like mentioned above may actually cycle the action already with no changes.

Re: I need to talk to a reloader with depth

125 grain Speer TNT over 45 grains of Varget. Gives around 2700 fps and I've shot some tiny groups with that combo...it's my go-to close varmint load for my Winny. This bullet sometimes fails to exit coyotes, so overpenetration on a larger target is not a problem.

There are book loads for this bullet down to below 2000 fps, but I doubt they'd reliably cycle a gas gun.

Re: I need to talk to a reloader with depth

Richard Franklin has some 30 cal 110 v-max vids that disintegrate on groundogs at 300 WSM velocities,check them out on his site.

BobNC may also have the answer.
