I agree with you on excessive abuse on the one handed racking of the 500. This introduces unnecessary stress to the parts much like dry firing a bow/crossbow. I can never figure out why anyone would want to abuse there equipment in such a useless manner. Certainly, there are instances such as Dave had mentioned where it is necessary but to do it regularly is stupid. But, it's his stuff and he can do whatever he wants with it. The 500 could probably take the abuse being built to take on the recoil of a 12ga but every mechanical object has a breaking point. By pumping the gun harder than normal just accelerates the wear and brings the failure(s) sooner rather than later.
