I've often wondered if the "sticky" A-frame bullets could be powder coated (and sized after if needed) to reduce pressure and increase velocity. A direct comparison with all other variables held constant could be interesting.
Sir Bevan, Interesting. I never thought of that. There will be some spring-back. Soft copper jacket and soft lead (bonded) cores with a thick copper partition in the middle. If it springs back by .002": A .458 A-Frame pushed through a 0.455" sizer might spring back to .457" and get painted up to .458" after degreasing. Or, squeaky clean bullet painted to 0.459" then pushed through a 0.456" die might spring back to 0.458". Yep, latter sounds better.
Having a set containing .455", .456", .457", and .458" sizers would be a good start. It seems when I size a .463" PC-painted BHN25 hardcast with a 0.460" sizer, it springs back to 0.461". Soft lead sizes true: 0.000" TSX springs back 0.002", IIRC. Probably A-frame 0.002" also. A worthy experiment. Would have to try and see.
