Oh man look at all the old vs new vaquero confusion that still comes up. Now uberti's gonna add even more lol.
LOL...yup. To my knowledge,
Handloader magazine, and specifically Brian Pearce, provide the only load data for that niche of revolvers. At
www.loaddata.com loads for these revolvers are typically listed as 20,000 psi or 23,000 psi and recommended for
"U.S. Fire Arms revolvers that are 100 percent American made (after the year 2000), Colt New Service, Ruger New Vaquero and Smith & Wesson post-World War II N Frames, including Models 25 and 625 Mountain Guns" and now of course, recent Uberti's!
