[QUOTE="Trickymissfit, post: 533595, member: 25383"] in the original thread he stated they had a 700 chambered in 30-06. He was looking at the 6.5-284, and I said that they ate barrels. I didn't bother to state they also are well known for feeding problems, and case supply is always kinda iffey even on a good day. The 6.5-06 is a breeze to form as most folks know already. The 6.5AI is just as easy (neck down 7x57 brass, or neck up 6mm Remington brass, or even generic .257 brass). The reason I spoke of the 6.5AI is that it is a very good cartridge, and probably better for what his needs are than the 6.5-06 or the 6.5/284. It actually works better in the Remington magazine well better than the 6.5-06 when using very long bullets seated out near the lands. The gist of my post was that when you have a long action, then why not take advantage of it? 6.5x55 cases are not common in any place I shop. Yes they'll order it! I had a need for a couple hundred rounds a few weeks back, and three shops said they could order it in. I chose to use 6mm brass instead as I have about a thousand pieces that are virgin.
