Hey all....I've had my Mini-14 for 4 months now...It's a 181 series...with Choate EM2 stock...M-14 style flash hider...Bushnell red dot...and vertical foregrip.....Anyways since I got it I've only shot Winchester 55 grain FMJ and accuracy was not that great...I guess 4-5" groups......I bought some 45 grain JHP rounds and shot them today...WOW...What a difference!!!....My groups are now about 2".....I'm wondering if its because the twist rate is 1 in 10" and the lighter bullet stabilizes better or if its the JHP bullet that gives it better accuracy??....If i use 45 grain FMJ will I get the same accuracy??...Mini owners please inform me... Thanks...Wes PS...Yes..thats the mini-14 in my avatar
