6mm Norma BR or 6 XC

As a 300 meter prone competition shooter I am sitting on the fence to buy a new Grünig & Elmiger Free Rifle (ISSF). The only question which remains to be solved is the caliber. 300 meter competition is quite demanding, 60 shots + sighters in 75 minutes is hard on barrels and the accuracy of the guns has to be outstanding ("10" = < 4" and "X" = < 2" at 300 meter).

My questions are:

Does the new 6XC has an advantage over the 6BR for this type of shooting. Is it as accurate?

Would barrel life in the 6 XC still be acceptable for this type of shooting? The 6 BR gives me a usefull barrel life of 3000 - 3500 rounds (Moly coated 105 gr. Scenars in a Border barrel 30.0 gr. N140) which translates into roughly one season.

Eddie, even though I have a 6XC, I prefer the 6BR for 300 meter shooting. As you mentioned, the shots fired in a relatively short period of time are very tough on barrels and there is really no accuracy gain with the 6XC over the 6BR. I use the 6XC for longer distances (600 or 1000 yards) fore reduced wind drift, but that is a smaller factor at 300 meters. You can expect about a 25% reduction in useful barrel life with the 6XC compared to the 6BR. I still believe the 6BR to be the perfect 300 meter cartridge.

Thanks German,

It was my gut feeling also. I'll go with the 6 BR
