Hello all,
I have a brand spanking new Rossi R92 Gold Edition (beautiful rifle) in .357/.38 special. I was at the range 3 weeks ago and was shooting fairly rapid fire when a round blew out of the breech and broke the extractor and sent brass fragments into my face. Luckily I always wear eye protection so my eyes are still intact.
So I began a little investigation. The round was a reloaded aguila brass .38 special. It ruptured at the base. It appears the round was not fully seated into the chamber. This round was only reloaded twice. I have since stopped using aguila brass for reloads. I measured the case wall and it was 0.014" thick, just like all the other .38 special and .357 brass I have. There was no evidence of a bulge or weakening of the brass, but I don't like aguila ammo due to several rounds I have had that have failed to fire in .22 magnum and also .38 special.
On the day this happened, I assumed the bolt had been pushed back by the round exploding. But, I decided to do a dry fire test and see if the gun would fire without the bolt being all the way forward. With a empty case seated in the bolt under the new extractor I installed (from Jack First Inc.) I cycled the action and felt the bolt want to stop about 1/8th of an inch from being fully seated. Seems like something binds up with a bullet in the gun. I removed the case, and tried cycling again. Works just fine empty. I put some live rounds in and tried to cycle. No matter what caliber or bullet shape (LRN and CPFN), the bolt hangs about a 1/4" to a 1/8" of being fully seated to against the chamber. I can make it seat, but like so many other forums I had to cycle the action "with authority".
And thats fine, but my concern is this: I removed all of the ammo, and cycled the action to where the bolt hangs about a 1/8" or 1/4" from being fully seated and pulled the trigger. The hammer fully smacked the firing pin!! This tells me that the rifle will fire a round even if it is not fully seated in the chamber. I am 99% sure this is what happened when I was shooting rapid fire. I must not have been fully seating the bullets and one was weaker than the others and ruptured.
So here is my question, is this a normal operation of the Rossi, or is my rifle possibly defective? If there are any Rossi R92 owners out there, can you reproduce my situation and see if your rifle will allow the hammer to strike the firing pin if the bolt is not fully seated? Many thanks in advance.
I edited this to add a picture of the ruptured brass:
