Sent me scurrying home to research the heck out of 260 ballistics, barrel lengths, custom loads, etc - I didn’t haggle on price being asked, the only caveat being it was a refund if it couldn’t do what he claimed....which was a little outrageous tbh. But it not only met those claims, but exceeded them (FYI - claims were 3 inch groups at 500-600m with specific load). However - it’s not perfect. It runs a muzzle B, and is noisey as a 30/06. Top end loads recoil like factory 308 as well. The 260 lapua brass is gorgeous, but a bit exy. I’ve also used 308/243 brass.
With the “quoted” speeds - it will apparently shoot(need borrow chrono to confirm), I am at least mindful it might chew a barrel but x that bridge if and when...the fact is the ppl that built this knew a LOT more than me.
I can’t comment on the 7/08 but have read and heard only good things and the 6.5cm speaks for itself.

Creedmoor has awesome reputation for accuracy. It would be easier to live with. The tikka in CM is 1:8 twist which seems to suit heavier rounds than 110 - 140. Decisions. Anyway, I'm close, and I imagine a lot of you will think they're all good choices - LA-102 in CM, T3X in CM or 7mm-08.
Urastus wrote:I was wrong re the tikka t3x varmint. They have 6.5 x 55. It's strange - they seem to have all calibres except 6.5 creedmoor. That's the stainless, the blue varmint has different calibres again - still no 6.5 creedmoor. https://www.berettaaustralia.com.au/fir ... tainless--

in2anity wrote:I honestly think your overthinking it - in the digital world the CM vs 7/08 vs 260 vs 308 might appear different, but in reality they will all shoot exceptionally over medium and longer ranges (if your rifle and load is tuned).. There are far bigger variables such as windage and shooter error that will make you realize the comparison of these different specifications is much less of a significant factor than you might imagine... And you have to think about the cost of running it - 308 will be far cheaper to run, whether it be handloads or factory (but especially factory). Granted the 308 might jump a bit more, but if you get a decent brake and the rifle is on the heavier side, you can still get back on target in time to see the impact for shots 300m and beyond... I dunno, personally I'd be steering clear of 260 simply due to ammo/projectile availability. The other three - take your pic. But I say all things considered, the venerable 308 is tried-and-tested - the latest projectiles really aren't far behind the leaders. I say get a nice heavy barrel on a proven action, don't skimp on your optics, and then go out and shoot. There is a long road to travel before the characteristics of the CM vs 308w become a truly relevant factor...

buy a 243 in varmint config, dock the barrel to 20-22 and rechamber to 6mm dasher, jobs done

I can understand the addiction of speed. It really appeals to me. 3000 fps - whew! It breaks the sound barrier nearly 3 x
