Yeah, I know and its aggravating on two counts. One, that it happened in the first place, and two, I haven't heard a peep from Rossi except that they received my request for service. I'll be optimistic and just assume they've sent it to the technical department to be answered by an expert.Sure. Keep in mind that your .45 Colt Rossi 92 is built no differently than a .44 mag Rossi 92. Same steel, same heat treatment, same everything.
I'm not saying to load up your .45 Colt ammo to .44 mag pressures, I'm just saying a few hundredths of an inch difference in seating depth with mild .45 Colt ammo isn't going to create a safety issue.
I do think it's a problem that the different seating depth you show solves a feeding problem though. The round on the left should feed with no issues at all.
What pressure sign do we look for on 45 coltThe bullet on the left is a Hornady 45 Colt Lead Cowboy bullet seated to the length, 1.575, specified in the Hornady manual. The one on the right is seated to 1.535. It loads better in the Rossi at that length and leaves only a slight mark on the case. Is it safe to load these bullets to a shorter length if I reduce the powder load? Of course, I'd have to start low and work my way up to a velocity I like that doesn't result any pressure signs.

I wouldn't expect to see any at the velocities I want to shoot. I'm assuming they would be like Alaskamike says, flattened or cratered primers and maybe hard extraction. Since it's pistol brass I guess you might see split cases at the extreme.What pressure sign do we look for on 45 colt

Nicely done!Well, Rossi is sending me the things you normally get in the box, but they haven't said what, if anything, they are going to do about the scratched brass and clunky chambering. I lost patience and disassembled the gun and took a fine oil stone to the lower tang and bolt to remove the machining marks, burrs and nicks. I also took some 800 grit sandpaper to the sharp edge of the rear of the chamber. Then I installed a lighter trigger, main, stop and ejector spring. The action is easier and the trigger pull, which was higher than the 8 lbs my gauge will measure, a nice, crisp 2 1/2 lbs. It feeds better, but there is still a slight scratch on the brass, but its not catching like it was before. I didn't take much off the sharp edge pm the end of the chamber, figuring it was better to have to come back and repeat the process than to take too much off the first time.
Very good , you took the bull by the horns. Rossi won't care about what they consider throw away brass. Now it's out of warranty so it's all over now. Your now a R92 mechanic. Sorry but you can't have just one.

Nicely done!Here’s how the bolt looks after stoning it with a fine oil stone. It still has machining marks, but they are very faint compared to how they used to look. You can also see the safety delete button.

The difference in the chamber isn’t as pronounced. You can see the stainless steel follower under the barrel opening. I think I need to have another go at it with 800 grit sandpaper.
