What powder do you use with 100 gr TTSX ? Velocity?


It isn't just the powder. WW +P brass and loads. CCI 200 primer, 48.0g H4350, 100g TTSX, 3163fps. Bear in mind my Roberts has a throat so long I often joke the bullets couldn't touch the lands with a stick. A shorter throat would probably increase pressure, requiring a lower powder charge. Brass life has been excellent and primers look normal, but I can't vouch for the safety of using this load in any other rifle.

H-100V is the velocity champ in the .257R. Not quite as temp stable as H-4350, but works for me.

This load for a LA 700, COAL is over the 2.8" max for SA box mag. Even at 2.9+" COAL, it's jumping .03". The Brux barrel is throated a bit long.

It's a WT and hog killer.
