My Dad built a 6mm/06 in '64 and all it is, is a 243 shoulder on a full length 06 case. Has always shot 100 gr. Hornady Inter-locks from the start, shoots flatter than anything we have and has killed more game than anything. Built on a VZ-24 action, 26" barrel, use to use 4831, but is using some old powder he dug up a some gun shop. Barrel errosion was a concern for years, we finally cast the chamber and it looked just fine after 40 years of shooting. Mind you he don't shoot it everyday, but brings it out when a deer of coyote gets out in the middle of his pastures and wants to make a long shot. He's getting up in the years now and his eyes suck, but I wouldn't get in that rifles sites! Its built with a left handed stock, so the cheek piece bites me when I shoot it, so it will not do any us any good when he is gone, so it will be a safe queen. As for fire forming use cases filled with a charge and top with cream of wheat plug with toilet paper and fire form without a bullet!
