.35 is one fine bore size. I seem to have more of that than any other. Two .357 Contender barrels 10" & 12", .35 Remington 14" not to mention a Puma .357 and Marlin .35 Rem. lever guns, a .35 Whelen 700 Remington Classic, Colt Python, S&W M28 and lastly, a Ruger 50th Anniversary Blackhawk. I think the most fun are the Contender .357 barrels. Nothing wrong with other calibers as I'm partial to .30 caliber too as well as .25, 6.5, and 7mm but the numbers show a clear favoritism for .357.
