Lol, not really, my hot loads did...
My third trip to the range with my Ruger American 450BM and my 460 s&w charges yesterday finally started taking a toll on my optic and magazine. I have been loading all the way up to 460 s&w loads in it with no pressure signs but it's showing the outcome. My magazine started falling out half way through my shooting session and kept repeating itself every couple of rounds. Ruger is going to send me another to try.
My Nikon all of a sudden dropped vertically over a foot when shooting. It did this two more times but only in about 4" drops. I couldn't move my optic by hand but it looked like at one time the scope moved and the front bell banged against the ring. Nikon asked to send it back for repair. I drew a line on the first shot drop string. Looks like it would have been a tight group if they wouldn't have shifted down. I was using warne rings.
I've had a lot of optics that just won't adjust and lock up but never one that did this.
