[QUOTE="Fiftydriver, post: 37020, member: 10"] Long Range Demon TacKac, Keith, I was wondering where you were, good to hear from you again. Alot of my customers are saying the same thing you are but they are a little unhappy at first, at least the ones that had me build them 257 STWs. The nice thing about the AM rounds is that all that is needed to rechamebr a 257 STW to the better designed AM is to simply set the barrel back .200" and rechamber. The lose in barrel length will not even be noticed and only slight feed rail modifications are needed along with a RUM mag box in the repeaters, simple job. THe reamers should be here in a couple weeks I am hoping and I have a 1-8 twist and 1-10 twist 30" barrel coming for testing this hot 257 AM round out fully. I was totally floored when Richard Graves of Wildcat Bullets called and told me the B.C. of the 145 gr ULD bullets are initially showing a value of .738!!! For the big game hunter the 150 gr BCFBHP will be right at .6 which with a S.D. of .324 with a bonded core bullet will be most impressive, especially when loaded to the 3400 fps level. I will post any updates and especially the hard data when the rifles start barking!! Good Shooting!! Kirby Allen(50) [/QUOTE]
