Looking good Zeus. I had great results with the 87 Z-Max in my other 6mm AR barrel (like 1 hole groups) . If I were shooting rodents I would use the 75 or 87. I'm shooting at the MR-1 target so MOA is fine for my purpose.
Worked up a 95TMK H4985 load today, great results with that powder. All thrown with RCBS meter.
McGowen 20" barrel, Hornady brass no neck turn, 7 1/2 primer, TMK's are BN coated. Prone with bi-pod fixed 12X scope, 100 yrds.
26. Av 2609 sd 27 es 76 3/4" 5 shots
26.5 2659 15 28 1/2"
26.8 2700 1 2 5/8"
27.1 2724 2 4 1" worst group
27.4 2784 13 26 QL says danger but no major pressure signs
H4895 seems to work well in this barrel, all groups were Moa or less. The low es around 2700 is good and what I'm trying to achieve, low ES is what the long range game is about and I can work with seating depth/brass prep ect. I was in a hurry, shot 5 rounds first group and then 3 all other groups as it was CHP practice day at the range.
I'm going to test Varget and H4895 head to head before I run out of 95 TMK's. AR Prone Mid Range Match in 2 weeks for the accuracy real testing.
