That's awesome man! The craftsmanship of Stolzer is pretty incredible. It still blows my mind of how much of it was done with simple hand tools like a file. I talked to him recently about my 4 bore build to ask a few questions. Super friendly guy. I really look up to these rifle builders. They are keeping the embers burning of an almost dying art. I really aspire to be half the craftsman that they are.Yes I did, they were some of the first big bore barrels I'd made after coming to work for Joe. I followed that build too, it was interesting seeing someone build a rifle like that from scratch.
