I have been loading 180 grain FP sized 0.360 from a local caster, who happens to be an old friend which helps. I have used these loads in Enfield No 2's Mk 1, I* and 1** plus in four Webley MK IVs and a significant number of S&W M&Ps (some pre-Victory, a couple with the "V" prefix and one genuine Model 11). My load is 2.4 grains of Clays international with an OAL of 1.200". POA at 7 to 10 yds, so I have no complaints. Similarly, in the 0.455 arena, 3.45 grains of International behind a 0.454 250 grain FP for an uncut S&W HE Mk II or 3.20 grains in an uncut 1935 commercial Webley Mk VI Both are 1.100 OAL. For my cut Mk VIs (including two Enfields from the 1922-26 batches), I use 3.30 grains of International in 45 AR cases OAL 1.270. These are all to POA at 10 yds. Got to love those old pistols. Dave_n
