Now that Lapua brass is available for both cartridges, which is working "better?" I believe the .260 gives a "bit" more velocity, but in reality, how much more? Is the 6.5 X47 Lapua more "inherently" accurate? Does the 30 degree shoulder allow for less case trimming and upkeep? Will the 6.5 X 47 L barrels last longer since they use ? less powder?:) What are tactical and F-class/long range benchrest shooters using? Real world experiences and thoughts would be most appreciated?
 
What do you want to use the rifle for? What are your goals?

There is no such thing as a better cartridge. They all serve a purpose and the goal is to find the best fit to your needs.

They both shoot as accurately.

The larger case will always offer more speed for a given bullet weight at similar pressures and effective bore lengths.

until you get to 35/40Deg, shoulder angle doesn't really stop brass flow. you can make anything stretch if you push hard enough.

Bore life is determined by how you use it. The 47L run super hot will cook a pipe faster then a 260Rem run mild.

If both are run at the same pressures and use powders of similar "BURN" rate, the larger case will wear faster as you are putting more energy into the system.

ALL the 6.5s are being used to varying degrees of success in both shooting competitions. As I said before, best is better determined by WHAT you want to do with the rifle and the tasks it needs to accomplish.

Friend has same combination as one on video he has over 3000 rounds with Tru Flite made By Robinsons still shoots very very small groups.
Don,t know if you will get a 260 to shoot as well, I like the 6.5by47 case and the small rifle primer

One question: Is the small rifle primer an issue/problem in winter?
I was told by a Vermont shooter that 6mm BR does not work well in winter because of its small primer.

6.5x47

I shot mine this winter in 1' of snow. We were shooting out to 900 yards. It was the first time shooting this rifle past 200. Rifle shot around 3" for 5 shots at 470 yards. I was easily making hits out to 750 yards, in fact I don't think I missed till we hit the 900 yard mark, but my range finder was having trouble reading at that range. From my experience the 6.5x47 worked superbly in cold weather!! It wasn't -20C, but it was around -5C. I am using CCI BR4 primers and RL15.

I shoot equal amounts of 6BR all year long. My experience has been that 6BR shoots just fine all winter long. I do add 0.2gn more powder for my winter loads, yet use the same primer (BR4).
 
For me, the question was not 6.5x47 vs .260, it was 6.5x47 vs .260 AI. I went with the former for barrel life and not needing to fire form the brass.
