I have a ruger m77 in .44mag. Bushnell 3x9 scope, 240grn xtp's. It is my main hunting gun in the area where we go. It drives tac's at 100yds. 2 years ago i got lucky and a big 5pt stepped out about 40 yds in front of me and i got a good double lung shot on him. He went about 50 yds and dropped in his tracks. The exit hole was big enuff you could stick your hand in!
