I like a variety of bullets in the '06 case.
Anything from 110 grain varnmint slugs at 3,400 FPS+ to 220g bear bashers...at 2,500FPS +
Oh, I just noticed. You have a
.25-06.
Never mind.
Seriously, for a small caliber rifle like that with possible use on Elk, I would use the 100g Barnes TSX bullets.
