Hello again,

Can't remember the twist it was either 1:10 or 1:14
Mine shoots 300 garin pistol bullits, all the way up to 500 woodlieghs no problem

I have a local smith who made one of these for himself and has done atleast 3 others including mine.
If you cannot find someone local who has the chamber reamer and who can do the work PM me.
The extractor can be reworked.

Thanks
Nitro

Bonanza,

I loved it too that is why I added it to my sig line, just wish I had come up with it.

Cheers
