Well I'm going on my first elk hunt this year and I was sure my Savage in 270 was just marginal over 200 yards. So a quartering shot @ 300yards with a premium bullet is going to get the job done?
I made the important part bold there.
Personally, I think the premium bullet is more important at SHORT ranges, though.
But either way, use the best dang bullet money can buy, whatever THAT is, for hunting elk.
