??. How did you make out setting back the .204 Ruger chamber to the 20 VT? Same shoulder angle so shortening the chamber about 1/2" and adding threads should have been all that was needed?
I'am thinking real hard about doing just that for my rear grip Savage pistol. Be interested on how things came out. And problems come up?
Working on brass now. Full length size the .221 brass in the VT die and so far everything looks good. (except for the two pieces of brass I stuck in the die
