I have a Browning 300 short and love it. I use 130 grain Barnes TSX bullets with 67 grains of Big Game powder and Winchester brass. Can't remember the primers off hand. Very accurate round out of my rifle. Good luck!

out of a Winchester Mdl 70 with a 24" barrel, 5/8 three shot groups, works great on elk and deer!
LAST EDITED ON Feb-19-10 AT 00:22AM (MST)[p]accurate mag pro has worked awesome for me with cci 250 mag primers with my 165 accubonds I use 72 grains and get 3000fps. with the 125 billistic tips I use 77.5 grains and get 3450fps.give or take 10-20 fps it's been awhile since I checked them. both loads will put all three shots touching.Man I love reloading!
I don't reload, but I've shot about every factory load, and funny enough, the cheap power point bullets shoot the most accurate out of my rifle- under one inch. Better than the premium federals and winchesters.

I've got a Sako .270 that is exactly the same as yours.I've tried 'em all and it has always liked plain-jane Winchester Powerpoints the best. And not just by a little bit...
