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

Ive seen a original box of Remington Arrow 8 ga shells go for that price at auction. Id never pay that for industrial loads though the money just isnt there and they arent really that collectible.



When I pull apart industrial loads I just use a flat head screwdriver to unroll the crimp and salvage the hulls since it doesnt damage them. If you cut the crimp off you're probably going to end up with a 2 3/4" 8 gauge hull.

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.
