Sorry I missed that it was Tula an not the Blaser I mentioned, and it being steel casings. Still kinda scary, and I'd keep a close eye on her. As to .357 Magnum J-frames, I don't care for those at all, and feel even with the steel framed J's its just to much of a "good" thing. 38 Special is more than enough in those!
Well after less than 150 rounds of magnums, I concluded that they are impractical in a J-frame. I mean, really. But I don't want to rain on anyone else's party, and if they want to run magnums through their J-frames, well - it's their hands, lol!
But back to the Tulammo, I got rid of it more than a year ago. I run cheap practice ammo through it - which is what led to Tul. My empties extract just fine. But with Tul I had real problems getting them out. The first thing I thought was oversized chambers, but when I shot white box, it didn't happen. When I shot magnums, it didn't happen. When I ordered Fiocchi it didn't happen, or with American Eagle, UMC or any of the others. But they are all brass. I don't know what Tulammo is - if it is steel, or an alloy composed of steel and other metals.
