[QUOTE="NesikaChad, post: 253250, member: 7449"] While I certainly advocate the performance of the Ackley line of cartridges I also caution those who want them in a sporter type rifle. Magnum velocity cartridges accelerate barrel throat erosion. That is a common denominator that a guy can't get away from. All the fancy shoulder angles and neck lengths in the world won't make up for the increased heat and pressure these cartridges produce. Fireforming cases causes about the same amount of wear. This is also a truth unless a guy is willing to endure the nausea of the cream of wheat fireforming method. (I'd rather suck start a 1911 personally). . . A second barrel could be chambered, but then you have added expense. Is the slight increase in velocity worth it? That's a personal decision. I guess I have little room to talk as I own a wildcatted 338 Lapua Magnum set up to shoot 30 caliber 125 grain bullets at a peak muzzle velocity of 4375fps out of a 34" barrel. I'm betting I'll be lucky to get 500 rounds out of the thing. 102grains of RL25 a shot does not make this very economical either. It is quite graphic and the rifle will produce a sinus headache rivaled only by the really big boomers. Just something to think about. [/QUOTE]
