I've been using the 150gr Winchester power points for 20 years in my Rem 700 Classic. In that time my window of lethality has grown quite a bit to the point that now as long as I hit them somewhere behind the nose and in front of the rump they go down. The doe I got last year was a clean gut shot(flat out run at 40yrds) and she dropped in 3 steps. So sue me I didn't lead her enough. The longest shot I ever took was 120yrds, that one took 2 steps.
Don't know if it's the gun, ammo or just my confidence in both, but when it goes bang they just drop. I can count on one hand the number of deer I've shot with that gun that have taken more than one step. I'll never try another brand of ammo. If Winchester ever goes out of business I'll have to buy a case of ammo to make sure I'm set for the rest of my life.
Remember, shoot straight and shoot often.
Good... Bad... I'm the guy with the gun.
