My SIL wants to hunt with his Henry .357 16" bbl, using a 180gr. Fprn cast boolit, 13.5 gr. H110 pc'ed. I don't know what his seating depth is. Hewas asking me if I knew about what the velocity might be but I didn't know for sure...1300-1400 fps maybe?
Can anyone give me (him) a better estimate? Thanks Bruce
