As you dive down this rabbit hole, check out Pittman Bullets.

Dude, 3000FPS with a 325-gr bullet? Better get some shoulder protection!

 

[Ninering62]

No, all Luke's stuff is .45

I'm very familiar with ASG's stuff.
I asked bc I saw the 4895 & 530 powders listed & they are far more prominently used in .40's than the .45's. I have both.

Dude, 3000FPS with a 325-gr bullet? Better get some shoulder protection!

With my 45cal, I'm sending 350gr XLD's at 3,000fps with H4895.
I can shoot the 350's at 3,200fps shooting RL17.
LR Customs T-REX CSTM muzzle brake tames all that recoil.

H322 80g Gets you 2850FPS with a 300g bullet with built arrowhead rifle.

Are they "necessary"? No, however I've got an 80gr powder chamber in mine. The powders that I use (Benchmark, IMR 8208 XBR & H4895) all require powder charges MORE than 80 grains using 300 & 325 grain bullets…..which puts the bullet a little ABOVE the chamber. You DO NOT want the bullet inside the chamber the least little bit or you'll have problems. The theory behind powder chambers is that a short, fat powder column will burn more efficiently than a long powder column and result in less "fouling". I'm currently testing that theory .

Above is some good advice. I would definitely put one in.

Benchmark at Luke's recommend load and nsr bullets were half inch right out of the box for me.

 

[ECHOLS28]

If Luke built the gun Id call or email him about max load out of that.

Only thing I can add is the use of 10x Powder. It's my go to for accuracy and great speed. My McWhorter 45XML loves pittman 303HC bullet with 91 gr of 10x. Just over 3100. Fps. Shoots in the .2 to .3 depending on my ability that day.

H4895 is No where. I've been looking for last 2 years

Not to denigrate any advice given here, but your best bet on it is going to be whatever Luke recommends. He is the expert on them.

I have bugged him so much lol. I'm just trying to gather as much info on my own as possible.

 

[dodgefreak8]

Very doable Luke is a great guy to deal with. I could not shoot mine with out a break I tried about 10 shots. That was enough for me. Sent it back and had one installed FYI.

I had him add a 3 port side discharge break but it's going to be suppressed almost always

What stock you going to put it in

I watched a YouTube video of a guy using rl17 to reach ridiculous velocities lol. Took a ton of powder though

What stock you going to put it in

I think I'm going with an ag composites adjustable armor if I can ever get them to answer the phones or call me back
