Getting an AR-15 to "shoot"

[montana_native]

I have a DPMS 24" bull 1:9. I recently tried some 75 gr A-maxes that Savtac generously donated to me and was pleased to see that they shot about MOA at 2850 fps with Benchmark powder. I was well over magazine length with them.

EVERYTHING I have loaded for this gun shoots right around 1 MOA. The only difference I notice is on the chrono. What does it take to tighten these things up? I was hoping to try these A-maxes on gophers at around 4-500 yards while using 55 gr B-tips for the close stuff, but that's a small target at that distance. Is there a trick to reloading or is it in the gun itself?


Thanks for any help.

Sounds like you got it all dialed in. Have any of your buddys shot it for groups?

Try a aftermarket trigger and like ICANHITHIMMAN said have someone shoot groups with it .

I have an 8 twist 24" RRA, I shoot ultramax reman 55 gr to beyond 500 yards. this rifle regularly shoots 3 shot groups in the .2's at 100 yards.from my experience with AR's 1 MOA is average for the light barreled standard AR's , a varminter should do a bit better. who makes Panthers barrels? shaw?

I took it out again yesterday. I was able to get a 2 1/4" group at 300 yards and a friend of mine grouped right about 2". I guess its not really that bad. I may play with seating depth a bit to see what happens.

Thanks.
