I have an Ultimatum Precision Deadline Gen 2 with an IBI 26” 1-7.5” with 5R rifling in 6.5CM.
I typically shoot hand loads but last year I was on vacation and ran out.
I bought 2 boxes of FGMM with 140 SMK’s
1 box of Sierra Custom Competition with 140 SMK’s and a box of Hornady with 147 ELD-M’s
The Federal shot 1-1.5 MOA at 1,000Y.
The Sierra and Hornady shot .6 MOA at 1,000y.
Not sure I’ll be trying FGMM again if I’m in a pinch.
