Advocate - thanks, I've got a 325/350 gr NEI aluminum mould in .429 diameter. In .430 JDJ (0.1" shortened .444 in 14" contentder) with wheel weights it's accurate but doesn't expand at all. So I'm thinking of two options, wheel weights and also 1:10 or 1:20 or so (in the .444 in the '94 Win with 20" bbl). With the .45 Colt (16") it will definately be softer rather than harder (lower velocity) needing more 'splat'.
