My Swede is a Howa 1500 Lightning. It shoots pretty well with heavier bullets, but if it has a downside, it is that mine will NOT shoot lightweight bullets. Efforts with the Speer 90 gr TNT and the 100 gr Nosler Ballistic Tip were awful. And the 120 gr Speer and 120 Nosler Ballistic Tips were average at best, 2 to 3 inch groups at 100 yards. With the 129 gr Hornady SP and the 140 gr Hornady SP or Speer 140 gr, groups were much better, around an inch and a half. The Howa 6.5x55 has a ton of free bore in its' throat. I think I just can't seat the light bullets close enough to the rifling to get decent groups. I load all the ammo to an OAL of 3.15", the SAAMI maximum, if it can reach it. I think that would be one advantage of the .260 Rem over the 6.5x55 would be its' more conventional throating, since it was never designed to shoot 160 gr RN bullets like the Swede. I bet the .260 would shoot very well with the lightweight 6.5 bullets, although for medium to large game, the Swede is fine as is. I have owned a 7mm-08 remington in a lightweight Model 70 carbine, and was surprised at how hard it kicked. The Howa in 6.5x55 seems much milder on the recoil. When I finish shooting out the barrel in my Stevens 200 in .243, I plan on rebarreling it to .260 Remington and see how it compares. Oh, and by the way, Legacy Sports is planning on offering the Howa in 6.5x55 again after not offering it for the past 4 years or so. So you can choose between CZ, Tikka, Sako, and Howa for factory 6.5x55 rifles. I tend to think of the 6.5x55 as the thinking man's 30-06. It won't beat you up, yet gets the job done.
