I bought an M788 in 1970 chambered in 6mm Remington. Never fired a factory round, all handloads mostly with the Hornady 75HP over 46 grains of IMR4350. Killed a lot of Nevada jacks with that load. Later loaded the Hornady 87-grain SP over 44 grains of IMR4350, shot feral goat and deer. One black bear almost got away, so after moving to Alaska I switched to more potent rounds.
The best shot I ever made was on a male mallard at 250 yards with the 75-grain bullet (it was a 1/2 moa load). Clipped off his head, recovered him and ate him the next night. Four witnesses so it did happen. Statute of limitations has run out!
