I have a 26 1/2"x 8 twist Douglass barrel in a 6BR for a Savage, it has 2600 rounds thru is and been taken care of properly, but the 107MK no langer will touch the lands, so rather than scrap it, I want ro rechamber it into a caliber with a longer case so I don't have to do any threading to the barrel, I had a 243 in mind or a 243AI, any other suggestions that might be an optimum choice accurate long range varmint rifle with this barrel lenght.
thanks
