I hope this is the right place to post this. I bought a Euro Arms Replica of a Remington percussion revolver, Years ago at a gun show. It looks to be in real good shape. Lately I've thought I might shoot it, and have bought Pyrodex and caps, as I already had a couple boxes of Hornady balls, 451 & ,.454. My question is this, How large should the flash holes in the nipples be? They gage at about .081 which seems kind of large. for what its worth this gun seems to have an awful strong main spring.
