They still need to solve the anti-bounce problem. Seems they are running through recoil springs at an alarming rate currently.

I've been told removing a coil or two of the ejector spring may help but I haven't tried it yet. Never remove coils from springs. That is total hicksville engineering. It raises the spring stress. Dented cases is not something that needs fixing. +1. It constantly amazed me the things people find to...

Once fired brass isn't that cheap in Canada. Like I mentioned, we don't have access to military surplus brass here so finding once-fired commercial brass that cheap isn't likely. I'm not sure what you consider inexpensive bulk brass but I'd call up JR at TSE and see if he would make you a deal if y...
