If you like big bores/well.458,a 45-70 w/cast w/w slugs at 1300 will work for all gamg up to bad bear if you're not confident.Black bear is no problem,deer drop on spine shots,no blood shot but 1/2 in around hole.I like 7mm rem mag but head shots on deer,great for yotes using nbt's.I hav'nt killed anything yet w/.338rum,but with proper constructed bullets ie bonded core,should'nt ruin too much.Oh yeah,cant eat horns or head, good place for bullet.
Do I need these calibers? nope,could take care of most everything w/.22wmr if close and legal,.218 bee is good sub for neck/head on blacktail.Bullet placement and construction of same is important with precision accuracy. Bee uses 13.5 gr,.338 uses 85+, use only when necessary.
