Re: Rifle Thoughts
You'll have a much better bullet selection with the 30 cal over the 25, bigger longer bullet equals higher BC (Ballistic Coefficient), accuracy in Long Range is all about BC and to some degree velocity. I'd seriously consider the Win Mag or my favorite the WSM Like 6-Dasher mentioned, expense isn't really an issue, a little more powder is all.
You can always use lighter loads in WSM but you can never get the velocity equal the WSM or Win Mag with a 30-06. I was never a 30 cal fan until I got into the long range game, they're proven to be accurate, hard hitting and flat shooting. Downrange velocity and Energy are hard to beat.
