Thread: Breaking in the 260rem and load development

I have Nick Harvey’s 6th edition as well. Interestingly, my Sierra manual has no load data for the 129/130 grainers either and they make a 130. At the time, I think I researched a lot of H4350 loads as a comparison and some of those were over 45grains.
The old 260 load threads on here from 10-12 years ago has a fair bit of variance, some quite a bit over book max. The old story, every rifle is different, always start low, and worth re hashing the same questions every so now and then as things are changing all the time.
Now that I’m getting some of the reloading basics sorted, I’m going to start playing around with different powders. W760 for the 270 and I think it’s worth running some AR2213sc with the 140’s. Fun times ahead.
