I had one of the very first ones off the line with the sling swivel stud in the stock and a 24" tube. Did well on buffalo with 400gr TSXs and old fashioned 410gr Hornady solids. Damned thing was heavy, but it shot like a varmint rifle with 90.2gr IMR 4350 and F-215 primers @ 2450 fps. It also loved the 400 and 350gr TSXs with H-4350:
