During my up to now less than entirely successful experiments with cast bullets, I need to test whether it was my powder (Vectan Sp3) that was causing problems. So I picked a random yet safe load, and chucked a slack handful of match kings down range. The result was more than adequate accuracy for most short range applications, with reduced recoil and reduced barrel wear. Due to the reduced fill ratio, the group was strung vertically... to the tune of 1.25MOA, of which approximately 0.65MOA is the stringing, assuming the group to be circular otherwise. Aside from the random loads you get with the Lee die sets which sometimes show such a load with 2400, none of the other data booklets I have show them! Given that powder is horrendously expensive these days, there is certainly good and sufficient reason to use these slightly reduced loads with jacketed bullets, since in a full power case you are more or less halving the amount of powder required (e.g. 16gn 2400 vs 40gn N140) without compromising accuracy for all but the most demanding applications at 100 m. So, I thoroughly recommend Sp3/Ba6/2400/N110 or similar with jacketed bullets for 100 metre use.
