[QUOTE="Bart B, post: 109928, member: 5302"] Neat rifle; shot a few rounds through one in the early '60s. Pretty accurate with Lake City Arsenal M72 30 caliber match ammo, too. In that rifle's heyday, most matches were won using IMR4064 powder: 51 - 52 grains with a 150-gr. bullet. 46 - 47 grains with a 168-, 180- or 190-gr. bullet. IMR4350 was best with the 190-gr. bullet with 54 - 55 grains. Best accuracy was with bullets larger in diameter than .3086-inch; the military M2 173-gr. match bullet was great as were/are Lapua .3092-inch 170 and 185 grain match bullets. Those cut and/or broach rifled barrels had a tad large groove diameter of about .3083 and needed larger bullets to shoot the best. Winchester's own heavy match bullets back hen were about .3088-inch for that reason. Sierra's I've miced are only about .3082-inch except for the Palma ones at about .3084. PMC primers are the best these days; last forever and don't go erratic after a year like the others do. Winchester cases are great; much better than any military case. Full-length size 'em but don't the the fired case shoulder back more than .002-inch. [/QUOTE]
