I consulted with Hodgdon's site and called them to make some reduced power loads for the .308. I made these for my hunting rifle (mainly the Winchester 70 Shadow) and positional training.
Goal was to make an accurate practice load that reduced recoil, could be used for short hunting ranges as well and a bonus-poa/poi deviation be minimal from zero of current hunting load.
<span style="color: #FF0000">Hodgdon only has data and recommends the H4895 powder, follow the site advise and call then if in doubt.</span>
Used Federal case, WLR primer, Sierra ProHunter #2120 125 Grain PH and H4895 of course.
Following the 60% rule, minimum charge was 29.4 grains, I used 32, 33, 34 & 35.
Average velocity/group/deviation from zero at 100 yards.
32-2082-1.205-R1"/D1"
33-2128-1.090-R3/4"/D1"
34-2209-.990-R1.5"/D.5"
35-2276-.768-R.5"/U.5"
Of course I could beat my head against the wall to tweak it further, but I see no true benefit to the time, etc. doing so. I feel I hit the goal and for positional training, won't notice the .5" deviation, doubt who would(other than internet shooters)
Anyhow, thought I would pass it along and they list data for other common calibers as well.
I haven't tried H4895 for the 168 or 175 SMK's, but did use 39 grains of Varget for the 168 to get 2250 avg velocity for the same purpose, position training for the heavier guns.
For those wanting or needing the benefit of an easy load, it's worth it for the shoulder(post surgery) I also added a Brake to one and soon to do the other Precision rig.
