Having second thoughts on 260.. seeking wisdom

[Joe C]

I just switched from 260Rem to 6.5Creedmoor, there is certainly something to shooting a case with a 30degree ish shoulder.

So far after 1000 rounds my best groups are almost half of what my 260 could do.

Is the 260 hard to tune, compared to the Creedmoor, YES!

My 6.5 Creedmoor will push the same 140 Berger Hybrid, 140 AMax, 142SMK at the same speed with 2 ish less grains of H4350.

Did I mention smaller groups, my best 260 group was a solid .200 at 100, and the comps I shoot in that's more than ok, but the Creedmoor will consistently do almost half that, .095 is my best at 100 off a bipod, but most are in the .125 range

My next tube will be a 6.5x47, less powder, same speed, I hope better accuracy with better brass.

260rem is a good chambering, but there are better offerings out there that use less powder, which should equal longer barrel life, my 260 Bartlein tube went 4068 rounds.

You want more than 4068 rounds of barrel life??? :

lol - yeah, no kidding, I'm happy to get half of that on a match barrel.

My last two .300 WSM barrels went 1500, each. Oh, well. They were good while they lasted.

I've ordered some Lapua brass and will pick up the Hornady gauges (oal and headspace) and give it a go. I still have a supply of nosler 123s and AR Comp so we'll see how it goes.
