i shot several deer with a 35 and have seen dozens killed with the 30-30.....i have noticed that deer hit with the 30-30 run about 10-50 yards as if not being hit and then fall over dead.....when the 35 barks you see the impacted and you see the deer fall to the ground as if it were hit with thore's hammer.
I haven't killed a deer with a .35 Rem, but I have killed them with a 30-30, .270, and a .50 cal muzzleloader with a 460gr. conicle.
With all three, I expect a deer to run the 10-50 yds. before they realize they are dead, although I have had 2 dear die on the spot with the 30-30, and one with the .270. I have shot most of my dear with the Marlin 30-30.
Last year I shot a young buck right behind the shoulder with my .50 cal hawken with the .460 gr. slug at about 8 steps away. Not even 10 yards. He ran the usual 35-40 yds. before he died. Although I have experienced the dead on the spot shot, I wouldn't bet money on it with any gun. Maybe the .35 is the magic number.
