Velocity vs Penetration vs Expansion

Another thing I experienced this last year, and it could all be coincidence is on a slightly quartering towards full frontal shot I just clipped inside of near side shoulder and at the 20yds the shot was the hard cast rb did fragment a bit. I normally run Hornady and the recovered rb always have pretty good weight retention. These hand cast ones shot good, but I didn't like the on game performance? Course I could've shot better too, but either way I'm all stocked up on Hornady again.

The formula makes for interesting caliber to caliber comparisons and possibly a good starting point but does not allow for different powder granulations. I prefer chronograph results. My 58 caliber rifle with a 36 inch barrel continues reasonable gains in velocity up to 140 grains of 2F. The gain above 130 grains of 2f diminished up to 150 grains so that the increase in powder produced no worthwhile velocity gain. The wimp factor prevented testing above 150 grains. The 130 grain load did knock over a buffalo. That works for me.
