Bingo. I’d rather at least step up to something with a muzzle velocity of 2100 to 2300 FPS like a 35 rem. I like to watch my deer go down in sight. Been there, did it, done it, with pistol caliber rifles. I don’t like long trailing with zero to little blood trails with heart & double lung shots. These calibers will definitely kill a deer it’s just how long and hard you want to look for them after the shot. I get way shorter tracking and better blood trails with broad heads. All the reading I’ve done here that no expansion is needed because a 44 cal or 45 cal diameter makes a big exit hole is complete horse pucky unless your braking back bones and or bones on the way in so they shatter and do the damage an expanding boolit would do. Otherwise a non expanding hard cast sails right though like a FMJ. I’m sure PC, GC, and close to pure lead alloy would make all the difference in the world in pistol calibers when deer hunting.
