The 6.5x55 is very close to the 270. On paper the 270 would seem to hold an adge but out in the field the swede can hold it own. A good gun writer once summed up the old swede like this. It shoots as flat as the 270, hits like the 7 Mag and recoils like a 243. That does sum it up well. While I do not believe in strecthing the range on shot at big game, I have dropped a few critters at 300 + yards with the 6.5x55. To make matters better, my swedish mauser is the most accurate rifle that I currently own. With the 140 grain Hornady it will group 5/8 inch at 100 yards every time I go out. I just have an old world class Tasco fixed power 4X scope on it. Its been on there for about 15 years now.
