ohh, and the difference between norma brass and FC brass was not really noticeable, there was more difference in my shooting.
I'm no expert but the good boys on this forum put me onto that exact formula except I use federal match primers and if you start on the light side with the powder as someone else has mentioned and work your way up then you can't go wrong. I would buy a large quantity of powder as each batch can vary as I found out, I was using 71.5 grains but had to drop to 69.5 grains with the new batch because the new powder was really hot.
if you have not made up your mind yet, have a look at RL-26.
I tried 2217 amd 2225 i found 2225 to have slight edge on 168gr and above 2217 162 and below. Tikka action getting over 3050-3100fps 26" barrel
Tikka T3 - 162 A Max, 73grs of 2217, mag fit @ 2980 fps. also reload for another friend using 162sst with 73grs of 2225 at 3030fps also a tikka t3
Pro Chrono, lowest 3185 highest 3210 so average @3200
N560 would prob give better speed over the adi
