I tried 55gn cast in my CZ Hornet...shotgun pattern..A chap on the Isle of Man kindly sent me a selection of cast...the best I found was the NOE 37gn mould with GC...decent group with Green Dot.
I am currently using an H & N copper coated lead bullet of 45gn (not jacketed)......very accurate with N110....you can get them from Shooting Supplies, Luxembourg.
