Last winter I found a 22-250AI barrel on GB and only paid 25$ for it. It's a 24" med. weight with 6 flutes. It was already threaded for a Rem 700. It's a custom barrel and the only markings were "Spearfish". I figured I'd take a chance. I took it down to my local GS and he mounted it on a Rem 700 S/A I had sitting around gathering dust. It used to be my son's 243 but he outgrew the shortened stock last year and commandeered my 6x284. When my GS mounted the barrel the "GO" gauge wouldn't go. We had a barrel that had never been mounted and was short chambered. He happened to have the correct finish reamer and touched up the chamber to give me a slight crush fit so forming brass will be easier. I'm a big fan of "AI"ing cases like the 22-250 and any derivative of the 7x57. My 257Rob AI brass never has needed trimming and I'm on my 6th firing. I hate case trimming. I looked in my spare parts closet(some people get buy with a drawer);pulled out a B&C M40 stock and a H&S bottom metal I scored Ebay a while ago and now I have the coyote rifle I've wanted to build. This weekend I started taking lead measurements to load up some fire forming loads and I can't reach the lands with a 50gr BT. Uh oh, I think I found out why it was a 25$ barrel. So I rummaged around in my .224 bullet box looking for some longer blunter bullets and came up with the 64gr BSB - it works, but it is really long- 2.455 to the lands. Then I start wondering if the typical 22-250 twist of 1-14 is going to work. I grab a one piece cleaning rod with a free spinning handle, attach a new/tight brush and mark the rod with an ink pen. I push it through and get 2 2/3 rotations doing the math - I have a 1-8 barrel with a long lead! The 64grBSBs will get me going on the case forming but I don't have any .224 heavies and no load data for this. I love running down rabbit trails! :grin: If anybody has any experience with this please chime in. I'll be on the hunt for some .224 heavies.
