X-caliber 22lr

Got a new 22lr barrel blank from X-caliber a few weeks ago. This is for my 10/22 build for this year's squirrel season. It's a 20" long straight taper, .920" to .600". I took a standard 10/22 receiver and "trued" the face and bore, then threaded the receiver for .75-16tpi. I indicated the barrel in to under. 0003" over a 1.5" plane at the chamber. After threading I used a .5" ball nosed carbide endmill to relieve the extractor cut. I flipped the barrel around and crowned it. After the metal work was done I bedded the first 2" of barrel, lug, and the receiver. I will have a range report as soon as it's out of the bedding.

Looks nice. Looking forward to the range report.

A few images from the process. Those familiar with the extractor cut will notice the unsupported case wall, well this was an experiment with that type of extractor cut, it didn't work. I revamped the cut without relieving the case wall and it is working like a top. It looks identical, minus the minute notch in the chamber wall.

Nice! Can't wait to hear how it does. I have been happy with my CF X-cal barrels and want one for my CZ 452.
