Re: A191 Chamber?
I had an A191 and it was a .25 moa gun. In fact, one of my highest scores at HR was with that rifle.
I don't think accuracy would be an issue at all.

Re: A191 Chamber?
The irony was that was an HD rifles built by Jeff Hicks.
Brass life wasn't that good because the A191 is a high pressure load. I want to say I was only getting about 4 firings on average.

Re: A191 Chamber?
I don't the pressure off the top of my head. I'm sure it is in the high 50', low 60's. I never saw pressure signs at the load I was running, which was at 3050.
The thing from my understanding about the A191 (The Navy 300wm load) is it is essentially a chamber made for the 190smk specifically, I believe that is where the big difference lies. With a standard match chamber, as you know, you can run longer bullets. I wouldn't be surprised if faster velocities with the 190 would be obtainable. It would just depend on your requirements.

Re: A191 Chamber?
fwiw,
The particular rifle Mike shot was mine first. It averaged, by Oehler 35P, 3149 FPS with either FCC 93or WCC 95 and later. As a point of interest TRUE A191 chambers, those cut for NAVSPECWAR, were solid pilot reamers without a ton of attention. Recently they've gone to live pilots...fwiw & imho
Regards, Matt.

I rifle that I should never have gotten rid of.

Re: A191 Chamber?
I had factory black hills 190 smk loads touching 3000...from what the guys at Crane have told me the a191 loads are zingers..IIRC 3150 is what they expected on average (and seems about consistent with what was mentioned already)

Re: A191 Chamber?
A191 runs about 2975 fps out of a Mark 13 at 75 degrees, but the powder is very temperature sensitive, and at 100 degrees they're probably running around 3050.
