I shot this guy (my avatar) at about 80 yards. Muzzle velocity is 2950 fps, 7mm rem mag, 160 gr accubond. 1st shot through the lungs and he stood there like is that the best you got. Adjusted forward and put one through the onside leg and down he went...about another 150 yards straight down into a hole. 4 of my other elk were shot with a .338 225 gr speer spbt at 2500 fps from a 338 rcm...all 1 shot kills. My 1st bull a large 5 x 5 took 4 rounds from the rcm shooting 225 grain sst's...it was running through the timber and I may have been excited. All were shot on the Oregon coast.
