So, I went out to the range today to finally sight in the scope that came with my Remington 597 which I had bought from a fellow INGOer. As I was shooting, I had a FTF. I ejected the round and fired the rest of the mag. Everything seemed to be working fine. I inspected the round that wouldn't fire, and it seemed okay. There was a small dent in the rim, but, obviously, it wasn't hard enough to set it off. I assumed it was a light strike and loaded the round. When I fired it, it just didn't sound right. Plus, there was A LOT of smoke coming from the chamber and the magazine was still smoking when I dropped it and the follower was blackened. I didn't have a rod or anything to see if there was still a bullet in the barrel, and I sure as heck wasn't sticking my face in front of the muzzle. So, I packed it up and put it back in the car until I had shot my handguns (It's half an hour each way to the range. I wasn't wasting a range trip to shoot my .22 for 15 mins and go home!). When I got home, I stuck a long piece of trimmer line through the barrel, then shined my bore light down the barrel. The line went all the way through, and I could see the light shining into the chamber when shining it into the muzzle. After this, I looked through the muzzle with the bore light in the chamber, and everything looks good in the barrel. Nothing in the chamber is deformed or anything. Besides shooting that FTF round, did I screw up? Could it have fired out of battery and that be the reason for all of the smoke? I was shooting Winchester Super X, which I've put over a 525 brick of through this rifle already. Do you think it was just a bad round? I'm going to disassemble the rifle and clean super well before shooting it again. At that time, I'll be able to look for any actual damage, but I'm curious if anyone else has ever had a similar rimfire issue? Thanks!
