Why spend $100.00 when S&W will fix it under warranty and free of cost?
I concur that is true for improperly cleaned barrels, but not so much for cylinders. A dirty cylinder on a straight wall case will tend to grab case walls and cause extraction problems. This is more noticeable on revolvers because extraction is by hand rather than by a gas or blow-back operated slide extracting the case, but in extreme instances, even semi autos can exhibit problems, including ripping off part of the rim. However as I said with revolvers, pointing the muzzle skyward before extracting the shells will help prevent leaving debris in the cylinder and help ensure a more pleasurable range day.Way more guns and barrels are ruined by over zealous cleaning that by leaving them dirty. Black powder excepted
If you ream the aluminum cylinder of your 351PD, you will destroy it.
Because it is very likely anodized aluminum and you would remove the anodizing from inside the chambers. The anodized coating is harder than bare aluminum.
The cylinder is made from an aluminum alloy. What it is coated with inside the charge holes or even if it coated, I do not know, but I would not risk using a reamer on it. As Steelslaver suggests, a few passes with a bush and the proper solvent should be sufficient on all but the dirtiest of chambers. The fact that the OP's gun functioned flawlessly for several hundrend rounds before starting to seize up indicates a cleaning issue, even if that issue resulted from leaving the wrong cleaning/lube substance sitting in the chamber for too long. Again, chambers need to be clean.Will reaming the chamber remove enough material to get beneath the anodizing? If it does remove all or most of it, being on the inside of the chamber, would it make a difference?
This gun was purchased new in February, but thanks to a broken ankle immediately thereafter, it wasn't fired until April. I keep meticulous logs, and it had 277 trouble free rounds through it, getting cleaned after every range trip. Ammo is exclusively CCI Maxi Mags and Hornady Critical Defense.
Three days ago, I took it to the range, and after firing a cylinder, I couldn't eject the cases. I ended up having to bang the ejector rod on the table hard to get the cases half way out, and it was a &%$^ to get them the rest of the way out. I lubed the cylinders with Breakfree CLP and fired 2 more cylinders with exactly the same results.
I brought the gun home and cleaned it thoroughly. I dropped a Maxi Mag, then a Hornady cartridge in all 7 cylinders, and saw no problems. Went back to the range yesterday, and had the same results. This time, I had a dowel and a hammer with me. 3 cartridges pushed out easily, 2 pushed out with more difficulty, and 2 I had to use the hammer. Same results with both Hornady and Maxi Mags.
My wife has the same gun, purchased at the same time, build dates within a couple weeks of each other. She fired a cylinder from each of my boxes of ammo and had no problems, so it's obviously the gun.
I'll be calling S&W in the morning, and I'm sure they'll take care of it, but I'm wondering if anyone has seen this problem. It just doesn't make sense that after almost 300 flawless rounds this just comes out of nowhere.
The brass looked fine.
Yeah, that's what I'm going to do. I don't carry this gun, and I'm fine with letting things take their proper course.
