Disaster at the Range!

Well, maybe “disaster” is a bit of exaggeration, but a squib load is nothing to take lightly. I was shooting my Model 83/454 Casull this afternoon and had what I initially thought was a dud primer. I was wearing both ear plugs and muffs, my standard practice when shooting 454 loads, and heard a “click” when the hammer dropped. I kept the muzzle pointed downrange for 30 seconds or so to make sure it wasn’t a hangfire, and then tried to rotate the cylinder to extract the dud round. The cylinder was locked up tight! I thought there had been some sort of mechanical failure, so I called one of the gunsmiths at Freedom Arms for advice. The gunsmith (unfortunately, I didn’t get his name) was extremely helpful and spent a good half hour suggesting steps to get the gun safe and the cylinder removed.

It turned out that the bullet had lodged just inside the barrel, preventing the cylinder from turning. I was able to tap the bullet back into the chamber using a squib rod I had, but that forced the case back against the frame, so I still couldn’t get the cylinder out. The gunsmith walked me through removing the grip frame, hammer and hand, after which I was able to move the cylinder stop out of the way. I was then able to tap the cylinder out of the frame with a plastic hammer.

I was able to pull the bullet from the case using an inertial bullet puller. I originally thought I must have failed to charge the case with powder, but there was a lot of blackened powder in the case (see attached pic). I was using a moderate load of Alliant 2400…a heavier charge than a “Ruger only” 45 Colt load, but less than a starting load for 454 Casull. I’m aware that H110/296 can squib if undercharged, but I wasn’t aware of the same concerns with 2400. I’ve never had any problem with this load before, so I’m wondering if it was an underpowered primer.

Anyway, the gun is in pieces, so I’m going to send it back to Freedom Arms for re-assembly and a thorough going-over just to make sure all is OK. Hats off to Freedom Arms for their excellent customer service!

Put it back together yourownself. Ain't that hard.
The way that powder is clumped up. I say it's powder contamination as the cause.
How do you lube the cases for reloading?
Gary
have to agree. that powder looks it was contaminated with oil. Any chance you left oil on the bullets bases or didnt clean off case lube?

Powder does look clumpy. Curious about what happened with the bullet base? Folks at FA are wonderful. I once went from half cock to full after loading and fired the gun and unfortunately the cylinder didn’t line up perfectly. My mistake, but oddly I think the subsequent test group was better than the original 🤔.

LG and Lloyd, I can't explain the condition of the powder. I use a carbide sizing die and don't use any case lube. The bullet is an X-Treme 255 grain plated bullet, and it came directly out of the box and into the case. Could the load have been an issue? I was using 22 grains of Alliant 2400, which is less than a starting load for 454 (25.6 grains for a 255 grain hardcast) according to the Lyman Handbook. I'm not aware that 2400 is subject to squibs like H110/296, and I use it extensively. The only thing I don't know about is the primer. I was using a CCI 400 small rifle primer. Could the primer have had less than a full charge of priming compound? I guess there's no way of knowing...

LG, I'm sure I could have reassembled the revolver, but I've had the gun for more than 25 years and although I don't shoot max loads any more, I have fired quite a few in the past. I just want the good folks at Freedom Arms to check over the gun and replace any worn parts. I've noticed the cylinder has a little side-to-side play which probably isn't a big deal, but I'd like to have it back as tight as it was when I bought it.

How do you clean your cases before reloading?
When you see the cost to ship the gun, you may well rethink about shipping it.
If you do ship it, have the new style replaceable firing pin installed.

Gary,
Cases are cleaned by wet tumbling in stainless steel media, followed by drying in a case dryer for an hour or so. Then they sit for days until I'm reloading that caliber. Shouldn't be any contamination in the cases.

Yeah, I'm aware of the cost to ship. I paid I think 80 bucks a number of years ago to ship a Model 97 back to FA for repair. However, an FFL can ship a gun by the US Mail, so that's what I do. My FFL charges $25.

When I first started wet tumbling about a year ago, I would deprime cases before tumbling. But I finally realized that was just adding step to the process without adding any additional value since clean primer pockets don't function any better than dirty ones. So now I don't deprime. Not sure when I tumbled those particular 454 cases though, so I don't know whether they were deprimed or not when tumbled. Are you thinking a stainless steel pin might have lodged in the primer pocket? I guess it's possible, but I didn't notice anything unusual in the indented primer, and there was no pin in the unburned powder...so the mystery continues.

I dry the cases in a Lyman Cyclone dryer for at least an hour, and they come out hot, so I don't think any liquid could be retained in the primer pocket. I'm going to pull the bullets from the remaining cartridges so I'll be able to see if there are any issues with the powder.

Any updates?
LG
Finally got round to pulling the bullets from the cases, and didn't see any issues with the powder. I pulled five cases and all had exactly 22 grains of powder. No oil or other contaminant was present. I still had 9 or 10 cartridges left, and didn't see any reason not to fire them, so I did, and each functioned exactly as expected. So I still don't know what caused the squib. Since there seemed to be a full charge of unburned powder in the squib round, I can only guess that I had a bad primer, although that's never happened to me in over thirty years of reloading. So the mystery continues...

Powder burn won’t be sustained in the absence of heat and pressure. If a weak primer sets off a few grains of powder at the back of the case, but doesn’t provide enough “oomph” to ignite the entire powder charge, the pressure might just be enough to shove the bullet out of the case and into the barrel. That’s what I’m thinking happened.

I just don’t see a propellant issue since I’ve used this load for ages, and found nothing to indicate there’s anything wrong with the load. Out of around 50 cartridges in the batch, only that one failed to fire as expected. I guess it’s possible that some contamination could have entered the case, but it seems unlikely as I don’t use any case lube, the cases were all squeaky clean and my loading procedure is consistent.

I’ll never know for sure what happened, but my bet at this point is an underpowered primer…

Exact same event happened to me around 2001, except with H110. The published load was at the lowest listed which can be tricky with H110/W296 powders. Understanding that 2400 is different.

Had a light report upon firing. Have thought about it alot over the years, I do know that my crimp was NOT heavy enough in concert with the PUBLISHED minimum load thats NOT ideal or NOT even recommended when using H110/W296---at least from my perspective after that event. Could have been a primer issue and/or contaminated components as well ... I always thought my very potential dangerous mishap was sort of a 'perfect storm' of multiple issues. Regardless, hope incident always improves my handloading skills for decades to come. Whew!

In my 454 scenario, I think filling to at least 99% case capacity is optimal for H110/W296, my practice anyway.

Even with 2400 at listed data, there needs to be a tight neck and a secure crimp plus non-contamination and with a good/primer(matched to powder)-plus its full seating primer depth 'all the way in' ... are some added thoughts.
