[QUOTE="J E Custom, post: 1302990, member: 2736"] Threading seemed like the best way to maintain strength and only remove enough for the threads. I also drilled the existing flash hole slightly and machined a nipple that was a press fit on the threaded bushing so it would be tight when the bushing was threaded in. using a chamber reamer, I made a collet that perfectly fit the case and used it in my lathe for facing the bushing, boring the primer pocket and drilling the smaller flash hole. This was to assure concentricity of the primer and flash hole. It was a fun experiment, but a lot of work. but if it had made a significant improvement, I would have gone to the trouble for my match rifle. J E CUSTOM [/QUOTE]
