An acquaintance inherited a Schultz and Larsen M65 in 7x61 a few years ago - took us a bit of fussing, but we eventually found dies and created 80 plus brass from 7mm Rem Mag brass. He took a Sask farmland moose with a single shot, with that rifle, that fall. Since then, I have acquired a Schultz and Larsen M60 for myself, a healthy supply of 7x61 Super Norma brass and a supply of Norma factory 154 grain loads. Be aware that there is at least 5 grains capacity difference between the original Norma brass (with an "Re" on the headstamp), versus the improved "Super" brass. Outside is identical - all the difference is thinner case walls and shallower case head. All in all, an awesome step up from my 7x57! Phil Sharpe created the cartridge around IMR 4350 powder and 160 grain bullets. Norma's last loading was with 154 grain bullets. We used IMR 4350 and Hornady 154 Spire point bullets.
