It is rare for someone to be thoughtful enough to follow up on a post after ten years. That is just great that you found a rifle/cartridge combination that suits you!
It is funny that some on the board are still giving you advice on the purchase.
I shoot a .280 Rem. (7x64 clone) for most deer size game, and have even used it for American elk and African plains game with the heavier bullets. What bullet are you shooting?
