Mike, I've noticed that with the large bell objectives that there is only a RCH between it and the barrel. When the shot goes off, I bet that the bell is touching or hitting the barrel just through flexing. That can't be any good for any scope. If I ever win the Lotto, I'd invest into making an unbreakable scope and make a tractor-trailer full of green. Wouldn't that go over well, an unbreakable scope?
