223 1x9 24" bbl 52 grain loads

An AR won't have the same velocity, so RPM will be different. MV × 720 ÷ TWIST = RPM.
When a bullet approaches max (without destruction) any imperfection gets exaggerated.
That bullet is also rather long for its weight, so jump could be important.

I dropped my powder charge to 24.0 grains which brought my velocity to 3048 FPS (sweet spot for my AR using this bullet). I also seated the bullet .070" deeper as suggested to 2.185."Two five shot groups shrunk to 7/8" and 3/4"

I would like to dismiss the size of my groups by attributing it to my lack of skill. I'm beginning to think it takes A LOT of skill to group under 3/4 MOA. Bench shooting is also not my forte. Practically speaking however, a solid 1 MOA gun is accurate enough as the shooter remains the primary limiting factor.

This right here Bill, should be in your tag line. This is the unfortunate truth that: most don't realize, few will admit, and even fewer understand.

" a solid 1 MOA gun is accurate enough as the shooter remains the primary limiting factor". True that. Fits right in there with " A miss is 95% Indian and 5% bow ". I never owned a gun that couldn`t shoot better than I can!
