I've tried the 162 and 150 eld-x's. 1 1/2" - 2 1/2" groups.
WOW I'm shocked you got that kinda result, I've been able to achieve under 1/2" in 4 different rifles with the 162g ELDs. Some haven't been as fast as some like to push em but I'll take the accuracy over speed. Makes me wonder if you might have another issue. Good luck in your quest
