.500 Nitro,

Thanks for the response. I've been searching the internet all day, and I have to agree with you. It seems that many manufacturers have used the hidden fastener here and there.

I want a hidden fastener, because I just don't like the way the Greener cross bolt looks. I know that may seem wierd and I can certainly agree the Greener cross bolt is the most effective of the third fasteners, but it's my way of finding a middle ground.

What I plan on doing is buiding a .500 N.E. on it and I want that added insurance. If I could do it without a third fastener at all, that would be great. I was looking at the B. Searcy doubles and he doesn't have one at all. He does, however, indicate is actions have a "Double Purdey Bolting", but I'm not quite sure what that means. Let me know what your think?
