I have to agree with skeeter on this one. Accuracy is more important. I used to shoot 150 grains of Pyrodex pellets because I could and I thought it was cool to shoot "magnum" loads. I then started experimenting and found that 130 grains worked a lot better. I have that pushing a 200 grain shockwave. I have not had the opportunity to shoot at a deer past 130 yards. It worked well on a doe out to 130 yards though. I would suggest you find what load works best in your ml and practice with that at different yardages. Over 1000 ft/lbs of energy at 200 yards wont help you much if you can't hit what your aiming at.
