is there a huge difference between a 1:8 and 1:10 twist. i see here on
http://bullberry.com/csale.html that they have in stock a
22", 30-221 Rem, std. scope, chrome-moly, bull, standard 1:10 twist for $309
but from match grade machine it would cost about $450 for the same (i think).
i'm not sure that match grade machine can export.
do i need an export license to export a barrel?
can a us citizen buy a barrel without a special license?
