I have one in 50 cal.It shoots under moa out to 200 yards. I really like it. It uses the same frame. The breach plug is in the barrel. I have a 222 mag barrel. Also a 257 Ackley barrel ordered for it. The 222 mag barrel was one from the custom shop that had been ordered and cancelled. So I got it at a reduced price. They said it was a 222. When it came, it was a 222 mag. It is a 22 inch barrel, only thirty six inches overall. I call it Shorty. You won't be disappointed with the endeavor.
