Just picked up a TX 22 last week and on Saturday, I went through 8 different ammo boxes without a hiccup. Winchester, Federal and CCI bulk ammo all worked without a hitch. Even CCI Quiet worked, but of course, it didn't cycle the action but gave some of the most accurate groups at 10 yards. At 25 yards, I did as well as I've done with any other gun/caliber except for specific target guns. Very happy with the function and accuracy.
I was looking to get a Glock 44, but the gun reviews said that it was picky. Other reviews said the Taurus wasn't picky, even with bulk ammo and that is definitely the case!
I would have never bought another Taurus, but the TX 22 really delivers.
By the way, I loaded the mags like I load all .22LR mags: rim down, leverage into the magazine, stacking as I go. Pulling down on the mag spring was a PITA and there's a technique to that which I didn't care to learn since wedging is quick and works. I didn't see a need to use the loader, just another thing to loose.
