I was fortunate enough to be qualified to purchase two 40XBs & a single old 40X from the CMP from 2004-2007. The prices were right - in the $385 range, and the two heavy 40XBs were in really nice shape, and both shot really well at 50-100yds with the Lapua made Wolf Match Target & Match Extra I was shooting back then. I let a good friend have one of the 40XBs, and wound up pulling the bbls off the other two, then sending the actions off to Jonathan Elrod at Modocam Rifles for the conversion to repeaters using V22 magazines. I did the machine work to install a Lilja titebore on the converted 40XB, and did the same with a Benchmark blank for the 40X. Both shot very well with these custom barrels that I chambered with an EPS reamer, and I shot them in PRS-type 22rf matches at a semi-local club, being well pleased with both of them. When Vudoo released their Gen 1 actions, I bought one of the early ones and put a Krieger in sendero profile on it. The Vudoo was every bit as accurate - probably a bit better - than either of the converted 40Xs, and it ran smoother. Kinda makes me wish I'd have kept the 40XB in its original state as a single shot target rifle, but it's still an absolute hammer as a repeater with good lots of SK Rifle Match & Lapua Center-X. Photo is of the 40XB with 26" Lilja titebore bbl, in a Manners T4A in woodland camo w/mini-chassis, and Athlon Cronus scope. That Lilja bbl is one of the most accurate barrels I've done for any of my rifles, but it needs wiped out with Ed's Red every 125~ rounds to maintain that accuracy.
