-> Now I am confused. If that's the case, how do they build the
-> revolvers
-> that shoot either if you change the cylinder? The barrel remains the
-> same.
I believe that the groove diameter on the combo revolvers is .224.
Although the .22 s, l, and lr are .223 diameter, they just don't have as
tight a fit in the barrel as the .22 Magnum, which is .224 diameter.
.001" is no big deal when you are talking about the bullet being that
much smaller than the groove diameter. BUT, you don't want to have a
situation the other way around and have a bullet OVER groove diameter.
Pressures will go SKY HIGH.
