I'm swaging this bullet down to .330 and using it in an old military rifle with open sites. Most loads and bullets hit about 9" high with the stock sites but I found a load starting this bullet at 1900fps that shoots fantastic and right on the money at 100 yds. This could be a really nice mild load for this old gun and I'd like to persue it for deer hunting. Looks like it would still be doing about 1700 fps at 150yds. Do you think it would open enough to be effective?? I'm thinking I'd never recover one to check how it did.
