Resizing some "different" 8 gauge hulls

[Joe Plante]

As far as the powder being unknown, I get that. However, with a potential 60lb haul, determining what the powder is, its characteristics (burn rate, pressure build, density, etc.) is not that difficult to do and would provide me with years worth of usable reloading supply. I've done it many time before and I'll be able to do it in this case, I'm sure.

The powder used in industrial loads most assuredly isn’t the same or same burn rate as what is deemed appropriate for these old doubles . Nice idea but I wouldn’t chance it in any of mine .

I am wondering why you would need a low velocity commercial load. Close sections and fear of kickback? It seems to run counter to why you need an industrial load in the first place. From things I have seen in the European press, they have new shells actually at higher pressures and velocities from the normal industrial loads.

One other thing I found was that after working on a resizing method, and finally getting a few cases to try, I found that my Scott made in 1872 was actually chambered for the 8 gauge industrial shell head. On firing, the front section expands to the same size, and the original hull head fits perfectly. I have had the gun examined by several knowledgeable people (on British guns) and the unaminous opinion is that it is original and pristine. I wondered if anyone else had a British 8 they used and what is it's chamber.

Guess my advice would be, if you don't have a gun yet, don't prep a bunch of expensive cases ahead of time. I wasted a lot of time and money (and several cases).

It sure what you’re talking about ArtS- I’m not reloading for an 8ga. I got my hands on a ton of WW 8ga industrial loads and am salvaging the components out of them. I have no use for the hulls and wads/cards but I know guys do so I want to find out what not to do to render them unusable to the 8ga guys. I don’t want/need them but others might so I don’t want to wreck them

save those hulls....a box of 25 industrial shells are not that costly I see them on auction sites from time to time....there worth is being able to use the hulls in a 8 ga shotgun for hunting and such...charlie

Milton,
Started out trying to un-roll the crimp but took way too much time- I have thousands to get through. That’s why I started zipping the crimp off but my concern was the length and whether I was rendering them useless to guys that might use them- hence the jumping onto this forum, seems like lots of guys that know about loading for these guns

I was under the impression, perhaps wrongly so, that the industrial loads were 3 1/4". Wouldn't cutting just the rolled end only shorten them by 3/16" or thereabouts?

A kiln gun is a massive piece of machinery, making me think they might be pretty high pressure.

Maybe this will shed some light ! https://winchesterindustrial.com/loads.html

FWIW I’m partial to full length 3 1/4” hulls .

The high velocity loads are 3oz at 1700 fps and 33k psi I believe. There used to be a guy who built and sold 8 ga industrial single shots on GB for 3k, he used a state arms 50 bmg action since its the only action with a large enough bolt.
