[QUOTE="Leslie Sapp, post: 1404089, member: 74272"] "If it were me, I would probably use Hodgdon's 280 Rem data for the 140 grain partition for the SGK, working up toward the max." That's exactly what I did. I'm loading for a Model 70 featherweight, 22" barrel. The Hodgdon Hybrid 100v data for the 140 gr partition out of a 24" barrel shows a 50 gr starting load and a velocity of 2669. The max load is 54 grs and a velocity of 2847. I put together three rounds of 50 grs of Hydrid 100v, winchester brass, CCI magnum primer, 140 gr gameking, COL 3.230. Those three rounds, the first I've fired from this rifle, made a .731 group at 100 yards. I'd be ecstatic at that, except the chronograph average was 2940..... No pressure signs, period. If it were close, I might call it good, but 100 fps over the listed 24" barrel max from a 22" tube from a starting load makes me a little cautious. [/QUOTE]
