a twenty cal barrel, have the chamber body made for a 22.250 and the neck for 20 caliber...
I'd be shooting it with 24 NTXs, 26 gr Varmint Grenades and 32 V Max and Nosler's 32 FB Tipped and HPs.
as far as the brass being necked down to a 20 caliber neck.
I have a die for that from Hornady, a universal neck die they make.. I bought that for $20 a long time ago, to neck 223 down to 20 Practical...
and a 22.250 body die....
was thinking 20 to 22 inch barrel, heavy magnum contour....
roving varminter as I call 'em.... going walkabout with it...
the brass and the case wouldn't be an issue....or dies for it..
the 223 seating die works just fine on the 20 Practical, so I am sure the 22/.250 seating die would pretty much do the same....
or go crazy... how about necking down a 220 Swift? That would fit over bore.... but doing Blue Dot in either would be no real issue...
not practical, but certainly no issue.
