Well.... I have a lot of firearms that have been reliable 99% of the time...
I also have some that I have not used enough to make a judgement...
However, of the ones I have used a LOT, most have had at least a bobble or two...
My pet M70 .280 has had some trigger problems, as has my M700 Mountain Rifle in .7-08..
I've hunted with several auto shotguns and all have been mostly dependable, but all of them have malfuntioned at least once or twice..
I have a Browning Citori whose safety binds once in awhile...Enough to make me miss a few birds over the years..
One gun that has ALWAYS funtioned flawlessly... An Ithaca SKB M 100 side by side in 20 gauge... I've had it for over 30 years, and shot 100s, probably over 1000 rounds through it, and it has never missed a lick...
