I have shot undersized, in fact only .0005" larger than bore diameter pure lead bullets in a breechloader and achieved 2" - 5 shot groups at 200yards, MOA, with aperture sights. This proved the undersized bullets obturated perfectly, BEFORE they left the case, as there was no leading, the bored wiped clean of the fouling of 5 shots, with a dry patch. Thus, I assumed the bullets obturated before moving very far if at all, from the case. For this to work, there must be room in the case/chamber for this to happen, I also assume. |
