I set out for the range with three 45's today.
My P220 has fed and fired everthing I've fed it, but this was my first time using steel case rounds.
No problems in over 100 rounds and shot it very accurately.
Same story with a Kimber.
Not so with a Ruger P345. She started to choke almost right away and within 12 rounds would not feed.
This ammo cost me $10 a box. I'll be getting more.

The fact one of my guns choked on the ammo, I would NOT be getting more. Lots of controversy over steel case ammo. I won't put it thru my guns when for a couple $$ more I can shoot better brass cased, JMO.
