Nothing wrong with the way I mount my scopes, they are always locked down properly and don't move,marked with nail polish to be sure. Maybe I can put this in a different way, I'm using the 454 Casull now for a while, the recoil is incredible, but I can maintain a good hold and aim to control top end loads for the casull in a hunting situation, In saying this, there is few scopes or even reddots that can take the abuse of the casull, a matter of fact I called a few corps, and they would not guarantee that the scope or redot type scope would hold zero, but they would refund if not, and they have. Guys I been a seasoned hunter for 25 years and have bought every thing under the sun to improve my hunting skills, in doing so I have found that(Battery's) are not reliable at all for the most part...The recoil of the casull is much more than the 500S&W even 400gr bullets, I bought mono grips for the revolver, this helps me but not whats on top. So far the top end Bushnell scope has worked fine and maintained zero. At one time I owned three RedDot scopes, two were for rifles and one for handgun, One of the rifle reddots the knob fell off, then the lens in the front came loose, got rid of it, the other had no magnification just a dot, didn't give me much more than my own eyes with open sights, one thing I noticed is you really can't see your waiver like you can with crosshairs. Its all preference, but I like simple, less moving parts, NO battery's
also I prefer a fixed scope for a revolver,, like I said no moving parts, I'm not going to be shooting over 100 yards no need. Remember I'm old school, set in my ways, they seem to work, no need to change. I like to end this with saying I like the attributes the reddots have produce in the field, quick acquisition, easy focus, I understand these are very good attributes, I can't let my self trust batteries. Very cold temps have weird effects on batteries, I have hunted very cold climates in the past, Last year hunted in ten below zero for german boar in Upstate NY, my digital camera would not work froze all the gears;) Yes you can carry all the backup battery's you want, but when you pull up to aim on a animal and there is no dot, what are you going to do, take a minuet to change your battery's, bye then you game is gone out of sight, this happened to my good old father once using my RedDot, yes he left it on, When it came time to aim he had no dot to sight on his game. He let the buck go. Maybe I have got a bad taste in my mouth when it comes to RedDots, bye the way the they were the original redot corp I bought those reddots. I guess this was ten years ago, so maybe they have ironed out the flaws, One of the dots had replaceable lenses that were colored. Neat idea just did not hold up. All my rifles have scopes as well. I guess I'm a good old scope man;) Aim small hit small. RAMbo.
