Seems a lot of folks who own the old Webleys are interested in recreating the original 200 grain 361 thousands diameter projectile load , but bullet molds in that size are hard to come by and rather expensive as they are all custom made . They cost more than I paid for the gun itself . But there are many ways to skin the cat . Some buy standard 38 cal molds and hone them out to .361 with a cast bullet and some valve grinding compound . That is one option . But why not kill two birds with one stone? Prevent leading in the barrel and increase the diameter of the projectiles at the same time . So how about powder coating ? Essentially you are adding a jacket to the cast bullet and thus some thickness . I experimented with it a couple of years ago and though I made some I never actually loaded or tried firing them .
I had some soft lead round nose, hollow base Magtech pills which were ideal and miked out to about 360 thousands of an inch after a double layer of powder coating .
With Dad's old Stevens 22 I was doing about an inch and a half group from about 75 feet .
