[QUOTE="Schnyd112, post: 1433013, member: 90453"] For a .260 your max throat/freebore on a reamer is going to be around .080 to still be able to mag feed. That leaves a lot of open air above the base of the bullet when you are loading 42-43g of 4350. You may get the speed, but in my experience it just isn’t going to be consistent over a competition season where you will shoot 1000+ rounds. My best loads were with 95-105% fill in the .260 with 4831sc. But I was losing any ballistic advantage of the larger case and actually shooting significantly slower than smaller cartridges. Rl 17 gave me speed, north of 2900 FPS, and es for a day was great, but comparing one day to the next the numbers were just never as consistent as they were with 4831. It just left too much open air and I think that played with the burn rate. Varget will fill your 6.5x47 case just about perfectly and I have seen one in particular shoot silly consistent numbers. 5 FPS extreme spread over two ten round groups. Shot a week apart. [/QUOTE]
