British Service Revolvers - which one to collect or shoot?

[CCAMERA50]

a.s.a.p. i will post the exact meas. -

well, the dia. across the lands it is .348 then the thikness of a single land should be almost .0077

then i think should be none problem to fit a soft alloy ( as you told ) lead bullet RN dia .361 ( or .362 , ....i will test )
and see more accuracy then the FMJ Fiocchi i tested first

correct ?
