never had an ounce of problems out of mine...and after seven gobblers and untold other game shot with it. the only thing i dont like is if dirty the rotating bolt head might not lock up......but now this is really dirty....like the time i fell on it in the sand after running to a turkey i shot....after sitting indian style for 2 hours ....lol...got about 4 steps and plowed face first into the sand. but im sure you'd have the same problems with any kind of gun....except maybe a break open design. But man I will tell you what, the rotating bolt....i think they call it the speed pump or something like that...is like greased lightning. i used it to my advantage two years ago when i had to take three shots at a gobbler after my wife missed it....my first shot was a missed snap shot....second same thing...third one i took him on the fly...with a scoped shotgun no less....i felt like king of the world that day....just goes to show you that aimed shots are better than superior firepower any day.
