I tried TulAmmo in my XDm 9mm. It jammed up in the magazine. The casings are rougher than brass. After about 6 rounds, you push down enough to get #7 in the mag and the 6 get stuck.Been seeing around some places that steel case ammo can damage your firearm. Just started stocking up on ammo but don't want to buy chappy ammo. Right now I have two 9mm's XDm and a Nano.
If you do get 10 rounds in they won't feed reliably. Had an unbelievable malfunction in an IDPA match. One round stuck part way in the chamber, one stuck facing backwards next to that one and a third facing up. Never shooting TulAmmo again in my XDm.
YMMV.
