Well, given all of the favorable comments in this thread about Hornady's 140 BTSP, I bought a box tonight.
I think I'll try them out of a Pre-64 Model 70 and see how well they shoot and how fast they go.
I'll probably start with H-4831 SC. My lot of RL-22 shoots very accurately but doesn't seem to chronograph as high as some reports I've seen. Ditto for RL-19, I get higher velocity from IMR-4831, for some reason.
