I picked up a 16" 450B upper from Midway several months ago for north Arkansas Ozarks whitetail hunting. It's had a total of 18 rounds down the tube, 16 sighting in and 2 hunting.
Killed a small doe in early October during our antlerless gun season.
This morning at about 8:30 I had this 9 point walk up checking some does. 250 grains of Hornady SST into his rib cage. Part of his lung was hanging out the exit hole.
It was 20° and I saw 14 does before he walked up.
