Before I started reloading for my 300rum I wasshooting remington 150 grain swift scirocco's and they tore the hell out of the deer,lots of meat damageand would not hold together. I shot a deer at about 100 yards quartering to me and it never came out found the bullet in 2 pieces the jacket completely separated from the lead core. I heard they made the bullets better but dont know I would try the 180 barnes tsx federal loads them. As for a smaller gun 243 or 270 im kinda liking my 243 works great on the deer and yotes.
