Yesterday I barreled a vz-24 with a long 30-30 barrel already chambered when I got it. I knew it would need to be turned shorter because of claw but I had to see what a detonated cartridge would look like with the deep chamber. I put a full power load in because I wanted it to blow out against the walls and fired it. I can not down load pics here but it was about 3\16th longer body and it almost looks like a miniature 300 weatherby. All fun must end and it now is fit properly but I kept the cartridge for laughs.
