Need of custom twist barrel

[358Scout]

I've designed a cartridge, and before anyone says - "Its probably already been done."

My answer is "No it hasn't as the principle behind its design has never been used."

The build to be is on a single shot action. Bullet -.377 as used in a 38-55 Winchester - cast, more than likely GC

Sorry, I need a 1 in 13 not 1:21.



Any idea who could produce a specific twist for new barrel?

Thanks

Contact every barrel maker who cut rifles a .375 barrel and ask if they will make a 21 twist.
