Does anyone have one or know of anyone who makes them? Are std GI mags usable w/ this caliber? AP

I built one in 17 Mach IV last month.  That is the same case as the 221 FireBall, just necked down to 17 caliber.  It runs fine from a standard magazine.  I could do one in 221FB.  Would just need to get the chamber reamer.

How long is your bbl and did you experience any feeding problems? I was thinking serious about building a 221 FT upper. AP
