AR-10 Project-X
« on: November 20, 2017, 08:38:22 PM »
Just full length sized the first cases for Project-X. This is for a AR-10 assembly.

Parent case .308 Winchester on the right. ☠️Project-X☠️ left.

Think of it as bad A$$ supersonic and dwarfs the .300 Blackout subsonic.

No spilling the beans Yorke!

I donít remember signing a non-disclosure agreement.... :chuckle:

I think the only thing that matters here is that somebody finally found a use for the 308 win case!

I remember that being done in the 1970's/80's a fellow screwed a 375 Win Savage Brushgun barrel on a Savage 99 that was originally a 308 and opened the barrel to 375-08.
After the first shot the rest are just noise.

Everything's been done over the years. Fairly few new "Mouse traps".

A guy that is a vault of knowledge is Dave the owner of CH4D Tool & Die. He's been in the wildcat game forever. I don't care what combo you come up with. He can pull a print and tell you the first year it was done. Some of these popular wildcats kicking around today were tried many, many years ago.

No matter how crazy your cartridge. Quality custom dies for 89.00 a set. Incredibly well priced, considering I have paid  $375.00 for a custom set of dies from RCBS, of course that was before I found CH4D.

C&H is an incredible die company,  I needed dies for a long obsolete European caliber that wasn't very popular when it was current, factory loading was suspended in the 1930's.  It was a 6.5 straight taper case that used a .260 bullet.  C&H had the die set on the shelf AND the bullet swaging die.
After the first shot the rest are just noise.

Took a little time to form and trim 50 cases. Loaded 10 rounds up with (.375) 250gr Sierra Gamekings.

I'll use the Gamekings to break in the barrel and get a basic 200 yard zero. Then I'll switch over to the Nosler 260gr Accubond's.

I'm still waiting on my Scope, mount, trigger and bolt carrier group to be delivered. It should all be here tomorrow.

.308 Win case left. .375 Raptor cartridge right.

I can launch the 250's out of a 18" barrel @ 2500 fps.

That gives me a little over 3360 foot pounds of energy at the muzzle and a little over 1800 foot pounds at 300 yards and puts a big hole in stuff.

First victim I imagine will be a coyote, then come spring. I'll load up some Accubond's and smoke some Rockchucks.

Most of my Black bear and Elk in the timber have been shot under 75 yards. This should be great for a in close heavy hitter.

I'm also looking forward to trying the Kinetic Development Group, sidelok 30mm mount.

I like to be able to swap scopes between AR15's and AR10's. I'm sick of throw lever mounts. Very few return to zero when being remounted.

It was supposed to be delivered tomorrow but I received a notification it won't be here until Thursday. All that festive extra, crap holiday mail.

I've shot coyotes with the .375 Ultra Mag/ 260gr Accubond combo.
