I use the 105 HPBT over 47.0 Gr 7828 SSC, or the same in RL-22, with fire-formed Winchester brass. This in a 8" twisted barrel.
I keep the data
from a thread a while back with lots of suggestions, like 41.5 RL-17 under the 105 HPBT, or Calvin's load of 48 grains of RL-22 under the same.
I know Tanner was working up loads in this rifle using RL-17, but since the 7828 SSC is shooting 1/2" groups at 100 yards, I haven't experimented much.
I may play with RL-17 once my supply of 7828 SSC runs out, if for no other reason than I have an 8 lb keg of it.
