drocs101,
I have used the 6.5x284Norma for the past couple of years and it is hard to beat for the criteria you have listed. I filled my limit this year on deer, all one shot kills, using the 140gn Amax ahead of 59.0gns of Retumbo and BR2's.
This load is averaging 3038fps and is sub 1/2 MOA out to 800yrds. That's as far as I have taken it. I'm shooting a stock Savage 112BVSS w/26" heavy barrel and Lapua brass. I don't think you'll be disappointed with this cartridge.
At 100yds it's a one-hole proposition and I shoot playing card size, 5 shot groups at 700yds. It will amaze you and your shooting buddies. Good luck. JohnnyK.
