6mm-221 fireball

[bobcat93]

Is it better to use 300blk brass and neck down to 6mm.
Or use 221 brass and neck up to 6mm.
Can someone also post
Some load data for this cartridge with velocity achieved and gun used barrel length bla bla bla..all the pedigree info..

Best to go up from 221

I had a reamer cut specifically for LC Whisper brass necked down.
Used it mostly for subsonic loads. Fun cartridge.
The barrel is still around here somewhere.

Necking up is your best course. Necking down from 30 cal. will give much thicker
necks, and make a lot more work.
