rrpalma Posted January 17, 2011 Posted January 17, 2011 Hello, I just got me a ne MR1 rifle -- this is my first 223 semi auto. I'm a little confused with regard to ammo, and would like to know your opinion on what ammo's better for a) breaking in the rifle, and b) accuracy. Should I go for 55 gr or 64 gr, both in FMJ? Thanks for your comments! Quote

Thanks for your comments! 55gr No need to go heavier for plinking/target practice. Also, MR1 is rated for 5.56 NATO, so if you want a hotter load with 55gr, it will handle it. Quote
rrpalma Posted January 18, 2011 Author Posted January 18, 2011 Thanks! What kind of accuracy can I expect? Quote
Alpengeist Posted January 18, 2011 Posted January 18, 2011 you can get some pretty decent groupings with it, accuracy shouldnt really be anything to worry about Quote
