I've shot .307" bullets in a Ruger .327 with a .314" chamber throat and .312" groove diameter and the accuracy was it hit the target I was shooting at some 15 yards away, yet when I shoot factory .45 ACP in the Ruger Redhawk the accuracy is exceptionally poor compared to my handloads with either .45 Colt or .45 ACP.S&W generally makes a 5 land/groove barrels, and Ruger often does 8 land/groove barrels on the 38/357 Blackhawks.
My 38/357/9mm Blackhawk shows no accuracy difference with factory ammo between these calibers, tested in a Ransom Rest. 9mm handloads have been the most accurate, testing .355 and .357 bullets. The smallest group was 1.4" with 24 shots at 25 yards using .355 bullets in the Ransom Rest. It's barrel slugged at .3577". Don't believe it when people tell you that undersize bullets don't shoot well (in a handgun).
Nothing is ever a given when it comes to shooting.
