I'm a firm believer in the need to get a high speed cartridge like the 243 up over 3200 to get that awesome shocking power one looks for. Hornady's 24/6mm cal 75 gr. HP and 48.7 of IMR 4831 will do just that. Very Accurate. Touching bullet hole's at 100 is the usual for this loading. Have been using this load for many years on MN deer. A good rib shot
on a 200 lb plus buck. That deer won't walk more than 25 yards at the very farthest after being shot. Most times its a matter of feet I've found to be more likely.
When field dressed. That little Hornady has a tendency to turn everything in the deer pump station into jello. As it dumps its entire bullet energy inside the animal. Seldom do you find an exit hole. Don't need one really.
But if you choose to use another brand bullet of the same weight. I can't garentee you'll get the same results as that Hornady gives. Devastating little bullet that Hornady 75 H.P. is.
