I don't own or have ever shot a 260 Remingtion. But I have and still hunt with a 6.5 x 55 all I can tell you is that while I would think long and hard about a 400 yard shot with any cartridge because I don't shoot at those ranges, since my home range is a lot shorter than that. That being said, Yea you put a good 120 to 160 bullet in the right spot like an elks heart or lungs and guess what you better have a real sharp knife and some meat bags. I have always looked at the 6.5 x 55 as being something of a pocket 270, And there are no flies on the 270 as a game getter. If I didn't have a 6.5 x 55 and wanted a 6.5 mm cartridge, I would buy a 260. And this if from a fellow that shot most all if his elk except 2 with either a 7mm Remington Mag or 338 Winchester Mag. Mostly with the 338 because I like the rifle. The other two that was with a 6.5 x 55 and some Norma 156 gr Loads from 21 years ago.
