[QUOTE="lerch, post: 106130, member: 3115"] I have one of the 270AM's, I absolutley love the gun. I can tell you that I will never not own a 270AM. For simple power, accuracy, and ease of loading it is a awesome cartridge. The 30" bbl is great and optimal I imagine. I have a fairly heavyweight bbl but I am gonna have it re-barreld after this fall to something similiar to Kirby's sporter weight gun. I used a Savage action in mine. DIes come from Kirby, or at least that is the easiest way I know to get them. The 277 AM is a pwerhouse but its only downfall is the added difficulty in prepping brass, this is a trade off for added case life. I think 4 firings with full tilt loads is probably close to done for the rem brass. With the 270AM all you do is neck down 7mm RUM brass to 270 and leave about 1/4 of the neck unsized for a crush fit, fire and BAM, you got AM brass. The 277 requires several stages of necking down and additional annealing, I think. The trade off is good when you figure in the added brass life and edge in power, just kinda a pain. I guess I cant say it is too much of a pain since I am fixing to have to do it for the 7mm AM anyway!!! good luck steve [/QUOTE]
