[QUOTE="Trickymissfit, post: 697451, member: 25383"] I think 5000 rounds thru a .204 barrel is pushing it. The vortex of the flame pathe is very close to the end of the neck, and I'd say 2500 rounds at best and yet still shoot tight groups. The Dasher case is nothing but an improved 6BR case, and will hold three or four grains more powder than the .204 Ruger case. The SPC case is shorter, but much bigger in diameter. Another one to think about is the old 35 Remington case shortened to about 1.75" in length. It's a .450" diameter case, and should give you a lot more capacity (if you can use that much). The 6.8 case is pretty much a shortened and rimless .225 Winchester. There is also a 20PPC, but how it shoots I don't know. How about the .220 Swift case shotened to about 1.95" with a .25" neck and 35 degree shoulder angle? That ought to flat smoke a .204 Ruger on paper. Cases are easy to come by, and the bolt head is not a serious issue. Even a slightly shortened 22-250 improved, necked down to 20 caiber is gotta be one to think about ( 1.375" shoulder/ 1.812" oal/ with a .250" neck). I think it'd at least push the 55 grain bullets to 3750fps, and be far easier on the barrel. gary [/QUOTE]
