billyb are you kidding? If you are speaking of old mauser rifles, they are probably the strongest and safest action ever made. The new mauser 96 actions may be considered strong, but they obviosusly cannot safely divert escaping gas and don't have a safty lug like the the old bolt actions. I have old mausers that shoot 160 gr bullets at right around 3000 fps- just as powerful if not more so than 'modern' rounds like .308 and .270.
As far as the 96 goes, I've seen an example of one, and didn't really care for it myself at least from a styling standpoint.
