Well, I finally had a chance to play with my new 6.5 MAX again today. Got a good load for the 129 Absolute and worked up another for the123 Absolute.
I have a neck crimp die ordered and it looks like it will take some crimping/experimentation to get it to shoot to my expectations. The rifle still will not group consistently. I'm looking for 0.5"moa every time, or better.
Anyway, on to the data: I'll post this in the spreadsheet shortly.
129 gr Absolute, 26" Brux 1:7.5, Tikka T3x action
68.2 gr RL 26, F 210, 3.020 OAL
3451, SD 5, ES 11
.676 group (sometimes)
123 gr Absolute, 26" Brux 1:7.5, Tikka T3x action
69.5 gr RL 26, F 210, 2.978 OAL
3556
got to 70.5grs, 3609, but got some bolt lift and backed off
Primer pockets seem to be lasting about 4 loads with the higher end charges for the 123s.
