I'm thinking of making one of my .223 rifles into this cartridge. At first I thought I'd run a 6x45/.223 Rem. The more I researched the 6x47 based off the .222 Rem Mag kept jumping out at me. I guess this was a popular cartridge with the bench rest crowd, until the advent of the 6mm PPC and BR cartridges.
I'll mainly be running 55-70 grain bullets for varminting, but I may decide to take it out for somthing bigger like pronghorn. Would it be worth my effort to throat it to run bullets up to 95 grains? 70 grains is the minimum grain I can use to hut pronghorn and deer but I would just feel better running a heavier bullet as long as I can get it up over 2500 fps at the muzzle.
I'm thinking a lightweight varmiter bolt action rifle with a 20" #3 contour barrel. I was thinking a 12 twist if I stay in the lightweight bullets, but if I go over 80 grains I think I'll need faster. Looks like H335 is one of the better powders as well for this cartridge. Anyone got any experience with this round or suggestions?
