RE: 7 mag bullet for moose??
I use a7mm rem mag butas of yet never a175 gr slug on any of the moose or elk I have shot. Majority were 160 grs. I personally harvested a bull moose with a 160 AB at approx 100 yards, 2 shots were fired but only one was required as both bullets found the vitals! The bull did cover 20-30 yards after the second shot took out his heart but he was dead on his feet as both lungs and heart were reduced to mush.
All said i have since switched to the 140 gr barnes tsx for elk and moose. Its performance and accuracy has been suberb. I have harvested 4elk/moose thus far with this bullet and recovered one bullet in a bull moose that was shot at close range. In this case it was a 1/4 away and the bullet travelled thru the lungs before exiting the opposite shoulder and coming to rest in the hide. Weight retention was over 90%, expansion was over double and very little meat damage. While Ihave long been aNosler fan the TSX has been to impressive not to load it for larger then deer game.
