[QUOTE="Buzzgun, post: 1234314, member: 4715"] I don't currently own a 260 and I don't keep chronograph data on the 6.5x55 rifles because the only shooting I do with them is informal steel silhouette shooting out to 500 meters (open sights) and plinking. For that use, I don't care how fast the load is. I am currently shooting 35 grains of IMR 4064 and a 140 grain bullet, a very mild but accurate load in my rifles. However, I do have extensive chronograph data for several 243s, a 25x308 (25 Souper, yes, Souper), half a dozen 7-08s and several 308s. There just isn't much difference in the behavior of a .264" bullet and a .284" bullet when launched from the same parent case. How about you, what does your chronograph say for your 260 and 6.5x55 loads and what type of pressure strain gauge are you using to determine that you are getting 75-100 fps increase [U]at the same pressure[/U]??
