Resizing some "different" 8 gauge hulls

[Joe Plante]

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.

edgarspencer- here are a few pics of the hulls (loaded and clipped open) Let me know if they don't show up and I'll figure it out. As you can see, my opening up the shell only clips off about 3/16" of the hull, just not sure if this is a bad thing or not.
