FA is very precise about diameters, yet, I reccomend slugging all guns before ordering a mold from LBT. You cannot take advantage of the all important custom diameters we offer unless you measure. In revolvers, always slug both cylinder throats and bore.
I hate to wait to getting shooting a new gun too, but hate it worse when I'm not happy with the results. If everything is done in order, excellent results are assured immediately.
