[QUOTE="AkleyFan, post: 2740730, member: 114323"] I have to add that I always send them my roughing reamer and spec my prefit barrels at .050" short, I then finish ream it to my preffered headspace spec as I'm very particular about it. I have custom reamers ground by Dave Manson that are specific to the brass I plan to use. All the 280 Ackley brass available that I've purchased in the past 4 years from Nosler and Hornady are well undersized and leave a pronounced doughnut/bulge above the .200 line (when used in a max SAAMI chamber which most manufacturers cut to) - at the start of the case web. This is not acceptable to me hence the custom reamers and reloading die sets. I've built rifles in 30-'06, 257 Roberts AI, 280 AI and 308 Win - they all shoot 1/2 moa or better. The 257 Roberts AI shoots in the .1's with a 100gr Barnes TTSX - it's a thrill to shoot a group like that built on a VZ-24 Mauser action and a McGowen barrel. My next build is on a prefit M98 McGowen 6.5 caliber barrel that my wife bought me for Christmas - not certain which chambering yet, but it will likely be a 6.5-280AI since I have an abundance of brass. I'll take a bit of credit for the success of my builds on McGowen's barrels. :) [/QUOTE]
