How to evaluate Mk1 barrels

[bentwrench]

Hello all,

I am getting a parts kit prepared to build into a semi Bren. I have a nice kit MK1* type from Enfield..

I have a couple Lithgow MKII barrels that are new, never fired, and have the nicest bores I have ever seen on any gun. I also have a number of MK1 barrels ranging from very good to OK in condition. I would like to use both types for display and shooting. I can feel a difference with a .30 cal bore brush between the barrels, some are defiantly looser than others. I was thinking of machining some hard wax slugs I could push through the barrels and then measure them to get an idea of the wear. I could also machine a step gauge and check each end as well. I do have a small lathe at my disposal.

What is the best way to evaluate the bore condition, and what are acceptable tolerances for the Bren?
