hillbillyhunter1,
Can't say how the bullet will shoot, but of you want to drop'em, try a break down shot. Might be a good option if you gun is already sighted in for your current load and is accurate. On a broadside shot or slightly quartering towards, find the ball and socket joint of the shoulder, then go ~ 3-4" up. Should break both shoulders, take out the lungs, major arteries and make for a short tracking job. Many guides recommend this shot to anchor deer on the spot.
My concern in switching bullets is if they do not shoot well in your gun. Then you may have adjusted your scope and have to try and reset for your old load on an already truncated timetable. If your current load shoots well and is accurate, I would not bring in any other variables into the equation. Look into the breakdown shot and good luck.
