On the 632 all the throats are .312 and all the cartridge chambers are .340. On my SP 101 the throats range from.311 to .314 and the chambers 5, .343 and one .342.What size are the throats on that 632, if you don't mind me asking?
My Single Seven had 5 throats at .314 and 2 at .315. Chambers were .338, .339 and .340. My Taurus had throats at half .315 and half .316 with chambers from .340 to .343.
I don't have a proper pin gauge so I was using a normal caliper and may be off a bit.
I'm sure of one thing though, Smith & Wesson really did a better job on their cylinder.
