I went through the same decision process several years ago. I am a big fan of the 6.5 bullet. For my high volume shooting, eggs shoots/informal club competition, and some mid range hunting I use a 260. I have been able to get accuracy that is on par with my 6.5x284's with he benefit of longer barrel life, 2-3x. Reloading costs differences are not that much, brass is a little less and your powder savings is about 10 gr/ round. I use 142SMK's and 140 VLD's in the 260. Velocities run 2800 FPS. For my serious long range hunting, or competition out to 1000 yards, more for varmints, I use my 6.5x284's. I use 140 Berger, and JLK 's that run velocities about 200 FPS faster than the 260. It handles wind well, and hammers deer sized game out to 1000 yards. Some will push a 260 to 6.5x284 velocities but I have not been successful doing this getting poor accuracy and case life. The most important factor with the 260 is to make sure you get a 1:8 twist barrel and a chamber that will enable optimum seating for the VLD style bullets, minimum 2.9" to the lands with a Berger 140 VLD. This will also enable use of a 142 SMK, 140 AMax, or the lighter weights. Overall, a 260 will do at about 700 yards what a 6.5x284 will do at 1000 or a little more from a ballistic standpoint. My loads for my 26" barrel 260 is Lapua brass, 45 gr. h4831sc, 210m primer, 142 SMK, .025" out of the lands, 2800FPS. Load data: My 26" barrel 6.5x284 is Lapua brass, 58 gr Retumbo, 215 primer, 140 Berger Hunting VLD, .072" out of the lands, 2970 FPS. Both loads will consistantly produce .25-.5 MOA 5 shot groups.
