I see people say that it makes a "big" difference, and that the mags are very picky. Well, I have FTFeed fairly frequently, to me, about 1 every 50 rounds, a lot more when new, 1 every mag. I've intentionally loaded these mags incorrectly, with several rounds stacked to the same side of the mag, and mine do not jam any more or less frequently. I've used mostly Fed bulk, and Win Xpert bulk(actually this has never ftf, but doesn't always go bang).

Has any one actually tried loading them incorrectly besides me to see if it really matters? Just curious, thanks
