20" bbl RRAs coyote upper 9"twist doesn't seem to shoot better then 1.5 MOA at 100 yds with AA2520 25.5grs Avg MV was 3,000. This rifle groups 55gr V-max in 3/4MOA with Bench Mark at 3175 Avg. On Box of Bullets Sierra recommends twist rates between 7-10" . What's the problem? I want a 300 yd coyote AR-15

You might try this load it sure works for me; Win case, CCI #41 primer, 65gr GK Sierra, Hodg; H-335 {25.0grs.} Vel’s run’s 2950 fps {tracking with M855} from my M4 clone 16.5 barrel and a little faster in the 20” AR15 with 1-9 twist barrel. Both rifles are very accurate with this load’…, it’s the only one I use in my gas guns now. It’s very hard on Yotes; waaaaay out there. Good luck. 436

436 How well ? What size groups? Today I was shooting 25.6grs of H335 behind this bullet. My groups were about 1.5+ MV of 3,025. Was I pushing it too hard? Best groups were IMR 4064 24.9 grs with a MV of about 2,850. Tighter group about 1.25 MOA IMR powder was the closest in burn rates to Varget that I can't seem to get....... Bought some Federal Ball ammo 193 55gr FMJBT those loads were HOT 3300 fps and produced 1"MOA I pulled the bullets on 3 of those bad boys. 27.8grs of Ball powder. This ball powder looked like either BL-c2 or H335 ,or maybe it was AA2520 or WW760 . ????? Dang I don't have a clue but shooting them you could feel how the action slammed harder back. Plus they shot well. So what is the moral of this story? Performace of that Federal Ball ammo was like throwing a monkey wrench into the mix?

Iron Worker My groups ran on average 1” or less depending on the weapon and the optics I had on it at the time. The AR15 A2 clone with a 20” 1-9 twist hovered around 1.0” for 3 shot group, using my ACOG .35x35 My Colt M4 clone with a 16.5” 1-7 twist holds a nice sub moa around 0.75” on it I have a Leupold Prismatic. The third rifle I used 65gr Sierra's in was my custom .223 Rem M700 LR with a 30” 1-8 twist Polygonal. I have a Leupold Mk4 M1 16X {This rifle was rechambered from .223 Rem to .222 Mag; just for fun, it shot fine as a .223 Rem, but I wanted to see if I could pick up a little more vel’s while using 80gr Mk’s for 1k matches.} When it was a .223 Rem I used the 65gr. Gk’s in it with the same H335 load and turned in many sub 0.50” five shot groups.
