Not recommended for sml priming modules - Lee Auto-Prime XR Rifle/Pistol Hand Priming Tool 90230

I bought this hand- priming tool to prime my priming modules for my muzzleloader. Maybe it's only me or the system I'm using, but I've only had bad luck. First time I've used it, the primer only seated halfway so it got stuck, and I had a difficult time getting it out. The second time I used it, I hyper-extended my thumb, and then it got stuck again because it only seated halfway. The problem is that with the system I'm using, you have to press really hard to get the primer to seat all the way. I've had better luck using the Lee hand press for priming my modules. To me the hand press takes about the same amount of time as using this hand- priming tool. And much easier. I don't know how good it is with priming ammo cases. Maybe it's better for ammo cases. But if you're using it for your muzzleloader priming modules, i would either get the Lee hand press or find a different brand for your hand-priming tool.
