Interest in the .260 Rem got started here right around 2001. I did the math comparing ballistics between the .308 and the .260, and the .260 became very attractive. Several of us built a few on the Savage 10FP actions and took them out to Whittington Center in 2002 to try at 1Ky and 1Km. They performed very well. I wish I'd had some experience beyond 300yd before then, but my best 1Ky score, last day of a week, was a 193(197?)/200, and I was very happy with it.
Soon after, the 6.5-284 became popular on the LR Comp lines, and made the .260 semi-obsolescent as a top performing LR Comp chambering. But it also ate up barrels a lot faster.
This presented a lot of folks with a quandary. Since I didn't have the resources to rebarrel once a year, I stayed with the .260, and had (have) to settle for competing mainly against myself.
I got a L-W 28" installation ready barrel, and that closed the gap a bit.
Soon after, we lost our 1000yd venue, and I wasn't shooting LR anymore. In the aftermath, the .260 languished, and I rebarreled the rifle in .30BR. I have a new Savage Predator Hunter .260 to carry on with .260, but it's only been shot a few times, and still really needs a load development project. Maybe I'll replace the barrel with the L-W I took off the original .260, since I already have good loads for that.
So, remember; things change.
