Gemihur sent this my way the other day. Great tool for this kind of stuff.

Single shot
If you go to AmmoGuide Interactive and sign in as a guest, so to speak,
You can explore chamber options from given conditions.
I go frequently for cartridge comparisons but data is based on averages and doesn't fairly represent a specific load
It is a GREAT source for reference

Hope this helps.

I didn't see anything on the site

I'm going to assume 220 swift or 6mm lee navy

 

[Crashdoyle]

So maybe if there is a 7mm mini dreadnought, I know there is a 6.5 mini dreadnought off the 220 swift case

Looked on the bullburry site and didn't even see one listed. Maybe post a picture?

New computer can't get pictures to load

Says bullberry
7mm Swift Custom

 

[gemihur]

It isn't an option at AmmoGuide
I'd suspect a mini-Dreadnaught relative also
Prolly made before Troy took over, otherwise load data would be made available
You've got a spooky one there, Doug
Great find!

Fred made a lot of custom chambers for friends. I had a 17 Thorpe magnum barrel for awhile. It was built for a friend of his. It fired a breech loaded 17 cal pellet with a 209 primer as the charge.


You will have to do a chamber cast to find out for sure. Another barrel I picked up one time was a 14 DKT. I did a chamber case using paraffin wax. It turned out to be a 14 Walker Hornet the DKT were initials of the person who supplied the reamer to chamber the barrels.

Just talked to Troy he said There was a guy that Fred made some barrels for that were based on 220 brass that was shortened.He thought that it was possibly one he had made for him.It looks to be a 7mm with shortened 220 brass looks to be 1 3/4 inches long

Sounds like somebody just wanting to keep wildcating alive. Sounds like Crashdoyle & Gemihur were the hounds on the scent lol. Keep us in the loop with how it all turns out.
