That’s how you shoot a group. Squeeze, settle the reticle and squeeze again, and repeat. None of this shoot one wait 2-5 minutes and shoot again and repeat.

I built it to shoot it matches where the COF is 15-20 shots in 90 seconds. Doesn’t doo much good to see how it groups with a full cooldown between shots.

If I slowed down a little I’m confident things would shrink to sub-MOA for a 10 shot.
 
Starting to feel like I'm struggling a bit.
20" Krieger M110, JP HP bolt, Aero M5 enhanced upper and handguard
Aero M5 lower, Larue MBT2S.

Small base die, bumping .004", Fed brass and CCI 250s. Trimmed on a Henderson.

The 169s show promise and the 175 Noslers as well. Looks like I need to back down on powder charges very slightly across the board. I also kind of suck at shooting a large frame gasser. I can shoot half minute with my bolt guns pretty regularly.

Shooting off a Harris and Protektor F class rabbit ears rear bag. PRS lite stock. Some of those fliers are me fighting with position. (Off a concrete bench), I did notice shooting prone things tightened up a bit.


Any thoughts, currently just loading everything to max mag length, haven't tried many powder charges but I would've thought with the Krieger I'd have se nice clover leafs with something at this point.

I have and shoot more than 1 Harris, so not knocking them.

Harris is tougher to load and has more hop than others. Esp on concrete.
an Atlas CAL or Accutac will likely shoot better.
Others probably too and havent used em.

Thats been my experience. Gas and bolt guns
