Has any one got any real good loading experiance with 60-63g bullets. I'm loading for a 20in AR-15 with a 1-9 twist and mostly just target type shooting, however ya just never know when an old coyote might take a stroll across the range. Ramshot and V-V powders are not readily available in my imediate vicinity. thanks in advance

25 gr of H335 and the 60-63 gr sierra. My old Hbar loves it.

Try AA 2015 should give you good velocity and accuracy.

With 60gr Sierras, try 26gr of Varget.

For the Sierra 60 gr. HP, I'm using 26.5 gr. - RL15 with Rem. 7 1/2 BR primers @ 2870 fps from my 24" bull barrelled AR15 (1-in-8"). This load is very accurate in my gun and deadly on song dogs. It is also accurate in my 20" service rifle (1-in-7.7") It should work well in your barrel.
