20 ga copper solids, What do you think ?

[nitro450exp]

Hello,

What to you think of this for a full bore slug ?

http://www.cherokeeforum.com/members/nitro450exp-10618/albums/other-ii/61020-imag0086.jpg

Solid copper, hollow base, 325 grain, 0.628" can swedge them down to 0.626", grooves are 0.625".
Should be able to get 1800 fps at 12,000 PSI.

Thoughts ?

Looks like the copper welding tips on our robots at the KY Truck Plant. Mighty expensive bullets for a shotgun. Would I be correct in assuming you are relying on the nose heavy profile to stabilize them, or will they be fired in a rifled bore?

Hello,

You are correct. Spot welder tips.
We change them after several shifts, I FP them in the lathe.
Cost me my time as they go into the trash if I don't take them.

Will be fired in a fully rifled H&R Ultra Slug and a Double rifle.

Well Good Times on the scrap factor. I think they will be more than adequate for anything that is worth putting in your freezer this year.

the pic isnt visible. i would like to see what you have.

Are you going to fill the base with lead? If you don't I think you are going to have problems with the wad getting pressed into the bottom and causing welrd results.

[stubshaft]

You could just fill the base with a fiber wad and that should preclude the problems with the wad.

[nanuk]

fill the base with lead and see how much it weighs?

[Frosty Boolit]

use tin and it can help keep the weight down. Brush it and acid flux and it would really make a strong bond to the cup.

I`d be careful about what you want to be doing here with those "purloined" weld tips! "Removal of any item from a GM facility without written approval and stamped approval with signature is punishable by dismissal". A neighbor cited this to me as chapter and verse after a fellow worker was nabbed walking out of the plant with a pocketful of these same tips. He said all used tips are put into a re-cycling bin to be returned to the tip making facility.Robert

They're not lead so I don't think you want them over groove size. The barnes copper solid rifle slugs have a lot of "grease grooves" to reduce the bearing surface.

Being welding tips they may be hardened from the work they're doing or it may be a very hard alloy. At the very least I think you should anneal them to get them as soft as possible.

I'm not really up on slugs, but I think any type of copper solid slug is always a sabot variety as well. There is not a lot of pressure to engrave the rifling into a copper bullet where the plastic sabot is easy.

Be cautious. Be safe. Good luck. Let us know how you make out. Inquiring minds want to know.

After sizing a few, I agree they will need to be annealed.
The sizer die I used was 0.622" my sizes on the grooves were off.
My memory ain't what it was.

I don't work for the big three, and these were slated for disposal not recycling.

[Blammer]

pour them full of hot lead that will anneal them. :)

Can you size them a 2nd time and get them small enough to fit a shot cup and let the plastic take the rifling?

That would sure make me feel better about your safety.

[nanuk]

take a steel bar, drill holes that just hold up the copper "Jackets"

find a RB mould that will fit/fill the hollow

acid brush the inside with flux

lay them in and set the whole contraption on the stove and slowly turn up the heat til the balls melts, turn off the heat

You could probably do 50 at a time.

[blaster]

Those look like awesome raw material. I would probably fill them with lead.

You might want to check out the "12ga from hell thread" if you are looking for raw power out of that ultra slug.

Keep us posted.
