Der Ami, august gunmaker Bill Slusser swears by the high quality of Colerain's gain twist barrels. I think several of our flintlocks built on Colerain barrels have gain twist, but I cannot recall. My son's child-size .45 is a tack driver. The real question is not if gain twist works, or not, but if it is possible to create a middle-ground twist rate that serves equally both long conical-type bullets and also for patched round balls.
