Not to hijack another thread. Being into milsurps at one time. I got a Swedish Mauser and was greatly impressed with the 6.5x55mm. As a reloader I figured the powder I used for .30-06 would be a good choice and it turned out to be great. 5 shot groups at 100 yards were as small as 0.75 inch. IMR 4350 was my choice under Speer 140 grain bullets.
