[QUOTE="Fiftydriver, post: 35779, member: 10"] Kac1345, My customers are getting in the 1000 to 1200 round life if they take good care of their barrel and use a high quality stainless barrel with a 3 or 4 groove rifling system. Also, a tight throat is a nessesity for any throat life at all with a round like this. If your smith uses a generic built solid piloted reamer to chamber your rifle, I would expect abotu 500-700 roudns of useful life. I designed my reamer with a throat 0.0002" over bullet diameter and this greatly reduces gas blowby and greatly saves on throat erosion. The STW and Banshee are the two biggest 257 rounds that I feel are useful and provide a long enough throat life to justify building a rifle in. I played around with the idea of a 257 RUM but computer models showed hardly any increase in velocity with available powders. Good Shooting!!! Kirby Allen(50) [/QUOTE]
