Yeah its no fun dealing with all the legal hassle sometimes. I contemplated just getting a fast twist barrel right from L.W. and having my dad machine it to fit the Ghost. Then if it shot slugs well id get a carbon fiber tube and mock up the shroud/stripper etc. The OE slug barrel twist is 1:17.7 and has been around for ages. I'd get the 1:15.7 twist if i could pick in 600 or 700mm if getting it straight from Lothar Walther. My fear though is Cdn border taking the barrel and it never makes it here

I haven't seen any reviews with the .30cal Brk slug barrel yet, I'd be interested in all the specs/accuracy for sure! I believe the .25 is the same twist as the .22 and .177.
