I have been trying to find a load or a way to avoid it, but I am afraid I am going to have to reline the barrel of my old 1892 Winchester. My local gunsmith does this and since there is no bluing left sweating the liner in after he drills it out isn't that big of a deal. I tried .313" lead bullets and even .315" paper patched bullets. After the first couple of bullets being somewhere near the target, the accuracy just goes out the window. With the shallow rifling, there isn't enough for the bullet to really grab hold anymore.
