RPR Criterion M24 Prefit

[AR-180]

I’m struggling to find a good load for this barrel. Does anyone have this barrel and a pet load for it?

Criterion’s M24 prefit is a .308 M24/M40 26” 1-10. They list the chamber as M118LR. Evidently, it’s now been discontinued by Brownells.

I’ve done several ladders using M118LR type components, but I have yet to find anything that has shot well for me.

30 gr of retumbo behind any 110gr bullet of course... it’s guranteed to work since you didn’t even mention a chambering.

Perhaps a bit more attention to the details would help you in your search for a load.

You had me going for a second. I’m wondering wtf I didn’t see a chambering. The attention to detail is a military thing. Normal people don’t have to worry with such trivial things when reloading.

I bet it’s 308 win or 7.62x51 NATO.

Assuming a standard M24 - 1 in 11.25 twist?

I’ve done ladder tests with 155 Palmas, 155 TMKs, and 175 SMKs using Varget, Lapua brass, and BR2s. I found nodes. I shot groups using the charges at the modes. The groups look like patterns.

I’ve shot Reloader 15 with 155 AMAXs.

I’ve burned up a lot of components looking for something that works.

I’ve emailed the company. They didn’t respond.

I’m a HM rifle shooter that was a varsity shooter and coach at a successful collegiate program.

I was hoping someone might have this barrel and a load that works. I’ve got numerous manuals.

My other rifles routinely shoot sub-MOA groups without much ammo testing. This barrel just seems to be a dud.

Don't email. Call the company. I have never had a problem as all my Criterion barrels have been half moa or better capable. I have dealt with Michael as well as Stephanie at Criterion and both were very helpful. They are busy, so you may have to call a few times to get someone on the phone.

Also, I believe Brownells has a satisfaction guarantee, but I have not dealt much with them.

I took the handguard off, reset the headspace, and removed the muzzle brake.

As I shot, the groups were getting tighter. But, I only had three rounds for the last group.
