I wish (yeah, right) I could get paid, but the market is just too small. Besides, It's more fun to horse around with these tools and realize, 'I shoulda bought one years ago.' attitude.
Anyways, I've been doing the Claven2 method for the past 20 years, and having my wife help out as the 'third hand' during the re-assembly process. Always give yer wife about 5 minutes warning, then progressively down to the 2 minute warning. Once you have the ejector spring aligned and in place (I'm pushing with a fired .30-06 or .270 case, since it's taller), I get my wife to tap away with a plastic hammer at the top of the extractor... that's all!
Now that I have this tool, life is a little less hectic and less chance to sproing the bolt parts all over the bench or shop floor...

Been there, done that!
Shredder, for a moose / deer/ bear gitter or zombie defense, NO you don't really have to go out and buy one of these tools, just use the "honey, be ready to come down to the workshop in 10 minutes." method!!

Worked for many years in my house
