I have an Dutch M95 KNIL carbine and an M91 Carcano long rifle that both fail to stabilize their respective bullets the majority of the time at 25 and 50 yards. Targets have bullet-shaped holes instead of round holes in them. Both barrels slug at .267 and Ive tried nominally .263, .265 and .268 jacketed bullets, with no noted improvement. The KNIL has dark, worn grooves with a fair bit of pitting, while the M91 has stronger rifling, but also a fair bit of pitting.
Between re-crowning, fire-lapping, and other processes, what steps would others suggest I take and in what order, to attempt to get these rifle barrels serviceable again?
