i was thinking about my upcomming project of building a vincent type in probably .50 cal for deer hunting. i'm getting readt to order a barrel and other parts and the question of twist came to mind.... i know most vincents were smaller bore, but i like the small details of a vincent that sets it apart from a hawken and wisconsin mandates .45 cal. minimum for deer, so i have to go at least .45 anyway. :grin: that out of the way, i would like, at least to stay as close to PC as i can and i'm sure he must have built some with bigger holes. now, most of his work was done in the mid to later half of the century, which brings up the question of,"would he have built a larger bore gun at that time and twist the barrel for round balls or conicals"....this, of course is just a speculative question, based on the fact that i'm pretty sure that historicly, they showed up about that time and there must have been people who were interested in keeping with the latest technology, just as now , but i don't really know if the conicals were commonly known about and/or available enough at that time, for someone to want a gun built for them. i want to make this gun with the premise that someone would have ordered a new larger bore vincent in around 1850-60 and wanted the latest and greatest bullet technology. does this make any sence? i know i can just build it for round balls and enjoy it, but it's kind of fun to have a reason to build something idenifiable but different. thanks for all your help. the more i think about these guns the more appealing the "true to tradition" part of it becomes!.
