Accurate load at 100 yds,,,,Accuracy is more important,to me, than firepower!!!You put the bullet where it needs to be and the rest will take care of itself!!!
Put a deer sized target out at 100 yards,,small isn't it..Wont be any bigger in the woods where you have a S.W.A.G. as to how far the deer is away from you.Not a measured distance, shooting off a rest and taking your time.
Read the Owners Manual and go from there... I have a Lyman GPR 50 cal,1-60 ROT,likes .495,PRB,80 grns FFF,. out to 100 yds. Shoot and Shoot often,learn your limitations and those of the rifle you are shooting and it will all come together
