Problem:
.270cal.Mannlicher-Schoenaur manufactured decades ago. Barrel in fine shape. I'm rolling 150gr. Nosler ballistic tips.
Rifle free-bore is very deep. The cartridge OAL ogive-to-lands is very long and if one seats the bullet .090" off lands the cartridge is still too long to fit into the magazine. I think the older European sporting rifles were made so to accommodate round nose bullets which of course have very short ogive to tip distances. Anyone have experience with round nose bullet ballistics relating to precision? Is backing the bullet > .100 off lands damaging to lands as bullet leaps forward? What would be a bullet recommendation?
Help!
