I have a .223 Ackley built on a Borden alpine which was 'smithed by Karl Feldkamp. I can't enough good things about either of them.
Well I guess I'll chime in also as another more than happy customer. Last September I got my Borden Alpine action/Kampfeld Customs built .243.
The Borden Alpine action sure is a nice choice for a lightweight build IMHO.
Action is slick even under nasty conditions and the rifle just flat shoots - Karl was great to work with as well, hope to have another one from him someday:)
