that's an interesting question. having it remain the barrel and being very hard to get down the bore all fits with it being a base wad. If I had some unfired loads from that company, I would cut one apart and verify that this is, indeed, a shot-cup wad and not a base wad. I suppose it could be a shot cup wad that was inserted in the shell BEFORE the powder was dropped. That would do about the same thing. There would be a delay between the primer firing and the powder firing which might be what the guide heard.

That guide earned his paycheck, tip, pat on the back, and beers for a LONG time.

It's not a basewad.

It's a Gulandi wad, just like it says.

Pictures are available on various web sites of what these in their several forms look like.

It had fire on both sides of it, we can see that. The rest is unknown.

It's good to look out after each other. If you hear an unusual report, do inform the shooter. He may not have heard it from his vantage point.

I have never seen a Gulandi wad, and I do not know whether they make base wads or not. It was an interesting idea.

fire on both sides would primer below, powder above - at least it could be.

I've stopped one shooter whose wad did not clear the barrel on a blooper. I don't know what would have happened, but it was easy to catch and fix - at a trap range.

I do not believe a primer would get fire through a thick plastic wad like this and ignite the powder, if it had been an under-shot wad with the powder on top of it, but I could be wrong.

I think I've posted this story before.
I was hunting with a guy who was using reloads. He shot them a lot at targets with never a problem. He had a few squib rounds while hunting though. The problem was the wads were slightly to small for the casings. The shells bouncing around in his game bag let some of the powder sift to the upper side of the wad. Causing a problem similar to what is shown in the photo.

Didn't we establish this was a shot wad and not a base wad? If it were in crooked, I'd think primer ignition and maybe partial powder ignition might burn both sides...Geo

My hypothesis.

For Wonko - it was the No. 7 shot

For the rest of us
Tipped wads occur in factory loads

Gun Club



Winchester Universal



Dissected. Note unburned powder past the base



Enough powder remained to propel the wad partially down the barrel as the powder past the base ignited and fried the plastic. The LOUD report (NOT a squib) was because of the functionally short barrel. Short barrel shotguns ARE loud.

Jay Menefee is a good guy. Dan might alert him to this thread

That's a very likely scenario Drew.

I had a bent Gun Club wad a couple weeks ago and caught it when the shell would not freely chamber. Bent at the crush section near 90 degrees.

Polywad uses wads designed for the hulls they use. There will be no powder migration if the wad is correctly loaded.

The point of my other thread was that factory shells are not necessarily of higher quality than those reloaded by someone who follows good procedure. Power driven equipment while equipped with lots of nifty safety features does not give tactile feedback to the operator.

No product is perfect.

Stan, I"ve shot a fair bit of primer wads in BPCR/TR competition loads. I find it amazing at what merer rifle primers can burn through. Shot shell primers could do much more I suspect. However, I don't think that's required here. Just moving the powder-filled wad down the barrel a bit until enough powder gets past the wad or primer fire going the other direction and then ignition occurs and the gun fires leaving the wad (mostly) in the barrel and scorched on both sides.

But who knows for sure? In any event, a significant disaster was avoided because of a sharp onlooker. That's all that matters.

On the 12-20 bursts there are two factors at work. First the 20 rim will hang in the forcing cone so there is a bit of clearance for an obstruction situation, however on the other hand it is so near the 12 that actual chamber pressure is raised as well. These bursts will be in the chamber/forcing cone area. The rim on a 20 gauge shell runs around 0.760". This will go beyond the 0.798" diameter of a normal chamber end of the 12 but will not enter the bore of even an 11 gauge @ 0.751", but will stop at some point in the cone dependent on exact angle of the cone. it will not enter any bore except something on the order of a chamberless gun. A barrel which bursts out beyond the hand doesn't sound ike a typical 12/20 burst but purely an obstructional burst, "Me Thinks" that one needed a lot more investigation.
