Mangled brass

#1 Post by Scrondar » Wed Nov 07, 2018 10:25 pm

So, I finally was able to take my Rossi 92 out to the range. All went well except for the way it chewed on the case mouth when ejecting spent rounds: Image

Sorry for the so-so pics; had to use my phone. Has anyone else experienced this as well? If so, what to do? I am about to tear this rifle down to do some Steve's mods, so is there something that can be done to the extractor to keep it from doing this to the brass? TIA.

Perhaps that’s an oversprung ejector and the dent is coming from the spent cartridge flipping hard onto the receiver frame or bolt. Steve’s mods fix that. After the mods the brass will form a nice pile off to the right a couple of feet away.

Is your brass 'to size'- Not too long?

I don't know if I'd be overly concerned about a couple of "knicks" in the case mouth... IMO, that's well short of mangled... :D

This is correct and why you should get Steve's DvD and parts. Both my 357 Rossis beat up the brass because of the excessive spring force but after replacing it, not only was the action smoother, there were no more issues with the brass.

BTW, if you think that those are beat up, don't even think about getting an M1 Garand, M1A, or stock Mini-14 (until you tweak it with a smaller gas bushing and then it's fine). That action style is famous for being hard on brass and Ruger's Minis have to be even more over gassed because idiots use cheap, weak commie ammo in them and expect them to still cycle well.

Yeah, but - it may be just the pic, but IMO the rest of the case looks like it's been used a few times too many...…

My 44 Magnum Puma will ding the case mouths sometimes when I smartly (quickly with force), run the lever. Easy levering hasn't seemed to do anything different to the brass. As noted above, Steve's CD is one of the best things an M92 owner can have, second to ammo...

Yes, I have Steve's video and parts. Haven't yet had time to tear the rifle down, but will soon. Hopefully, his spring will eliminate this problem. As for the brass, it was to spec. Both .38 and .357 were nicked equally, and this is the first rifle I've had that did that to the brass (except my Saiga .223, which dented the case mouth and body until I did a couple of mods that stopped it). Time to hit the bench....

Lee sells a chamfer tool that can smooth up the mouth edges. I use mine de-burr the mouth after trimming the length to spec.

Mine did that until I installed a reduced power ejector spring from Steve's guns. Steve is a member here.
