Re: Sako trg .308 handload
For my TRG-22 I load 175 SMK's, Winchester or BHA brass, 45gr. Varget, Fed 210M primers,OAL 2.884" which jumps 0.010". A friend with a TRG-22 uses the same length and our chambers measure the same to 0.001". Muzzle velocity on a 70 deg day is 2710fps. This load consistently shoots 3/4" groups at 200 yards. I haven't done any load development; just took this load from the internet and set the OAL for 10 mil jump. It is not worth trying to improve it.
For long range I am playing with 210 SMK's, 48gr RL-17, m.v. 2540fps. OAL of 2.940 barely fits in the mag, but has to jump 0.050". The 200 yard groups were consistently less than 1", a bit worse than the 175gr load - perhaps because of the longer jump. Jury still out but they should work better at 1000 yards.
