rrpalma Posted January 17, 2011 Share 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 Link to comment Share on other sites More sharing options...

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.

Alpengeist Posted January 18, 2011 Share Posted January 18, 2011 you can get some pretty decent groupings with it, accuracy shouldnt really be anything to worry about Quote Link to comment Share on other sites More sharing options...
