Remington used to load and sell a .451 diameter 185 grn FMJ Semi-Wadcutters and some outlets, such as Midway, used to sell them to reloaders. I still have some in my Loading Room inventory. They may still be available. Sierra and Speer also used to make them and they may still be available. Speers Bullet line changed markedly when they went to the TMJ plating Process for some bullets.JimL said:I've never seen a jacketed SWC. Have I just been non-observant?
