I've decided on federal hst's for my personal defense load. curious whether I should go with 180 grains or 165's or even 155's for that matter. shooting out of a glock 23. I know we're really splitting hairs here but I'd like to know what you guys think. It seems like when you use lighter bullets in any given caliber you get better expansion and maybe less penetration. Guessing this is do to the difference in the sectional density and velocity. But then sometimes you get bullets of the same weight that when they go faster they don't necessarily expand more but they seem to penetrate significantly deeper. ie. 38 and .357. So I guess a 2 part question. What's the relationship between weight, velocity, caliber, sectional density, penetration, and expansion. An whats going to be the best weight for the load I'm looking at. I'm guessing no one has a real good answer for the first part but I liked to see some discussion.
