I am totally lost for words.

I just picked up my Ronin 10mm last week. I am having similar issues where the cartridge is not feeding into chamber properly and I have to push up on the back of the round to chamber and then it comes back out. I've tried 3 different brass cased ammo (Magtech, Federal and Blazer) and they all have similar issues. Did you find a solution with your troubles?

UPDATE: After getting two additional magazines (both OEM) I did more testing by hand cycling. I tested Magtech, Federal, Blazer and Federal HST. In all 3 magazines the only ammo with feed problems was the Magtech. I inspected the rounds and I believe I’ve identified the problem. The cone of the bullet on the Magtech is a much sharper angle from rim to nose. All of the other bullets have a more rounded cone that is wider for longer before tapering to the snub nose. I think the narrower bullet in the Magtech is allowing the cartridge to feed further into the chamber before hitting the top and being pushed down. This is preventing the slide from being able to complete into battery. Just my two cents. Hope this helps someone.
