Hate to say it Firstfreedom but you'd be alone among millions calling an Enfield unreliable ... they are a most reliable battle rifle
Maybe I'm alone among millions, but two of the three that I've had, both No. 4s, would jam, jam, jam. Low jam, high jam, not stripping one off at all, you name it. With multiple different mags, same story. Tweak front left feed lips. Tweak front right. Tweak rear left. Tweak rear right. Repeat, repeat, repeat. Eventually, you get everything *just right* and the damn things will strip rounds off and feed very reliably. But I sure as hell wouldn't trust one in a serious fight. That's been my actual real experience. The Lee-Enfield has some great points, but I seriously doubt reliability is among them, relative to other designs. Now, since this is a magazine issue, if I had a newly manufactured mag, or one which had never been used, so that everything is perfectly in spec, then I'm quite sure it would be utterly reliable. Point is, with use, spit happens, and mags get bent, dinged, etc. This rifle is sensitive to any slight change in the angle of feed lips on the mags, and with them being removable, this makes them much more susceptible to bending & dinging.
Now, in stark contrast, take 98 mausers, k31s, 96 mausers, etc. - ultra reliable feeding, in my (albeit limited) experience. As you say, I could be the only one in the world. I would bet a thousand dollars right now, however, that I'm not the only one who's had jammomatic SMLEs (again, it's a magazine issue, but that doesn't mean it isn't a real issue with the rifle/mag combo).
Now, are Lee-Enfields FAST? Heck yeah, they are awesomely fast for a turnbolt.
