Thread: anyone shooting a 6mm Super LR?

I have a LH sako 85 sitting in the gun cabinet that I'd like to rebarrel to 6mm Super LR, 6mm Creedmore, 6-6.5x47 or 6XC for 105-108g vld's and maybe 115g out to 1000m

Cant quite decide which. Burnt my 20BR out in 1200 rounds and dont want to go there again so was thinking the 6-6.5x47 as its got 5g less capacity than the 243 variants, but been reading a thread on the 6CM (comp match) which sounds like a 243 AI variant and the guy says its good for 4000 rounds as the larger capacity allows him to burn H1000 (Ar2217) which is a cool burning magnum powder compared to H4350 (AR2209).

He has 28-30" bbls which is probably one reason H1000 works. The goto pwder for the 6 SLR appears to be H4350

Still thinking 6-6.5x47 is my best bet

Convince me on one of them?
