So in a recent thread I was looking at TB for 455 webley mk1(455 colt) and mk2 So after doing a little reading I thought about a recent purchase I have a Martini Enfield in 303(1876 receiver on a 1899 barrel) on the way but have been cautioned about using full power 303 loads in it due to age and proof rounds of the ordinal 303 black powder loads. So would tb work for this? I would be shooting either jacketed 180 gr or gas checked lead. Thanks
