If I were to buy a new muzzleloader tomorrow, I'd buy a Savage ML-10II and shoot smokeless loads in it. All the joys of muzzleloading without all the tedium and hassles of black powder or substitutes. The ML-10II is built to the same tolerances as Savage's CF rifles, and the ML-10II is the strongest and safest production ML in the world because it is proofed to smokeless pressure levels (129,000psi). The ML-10II is state-of-the-art in muzzleloaders. I'm obviously not one of those folks who think that the world is going to end because people can hunt with something other than sidelock long rifles. Inlines load from the front one shot at a time just like sidelocks. And let's not forget that smokeless powder is the ORIGINAL black powder substitute!
