There used to be a top of the line MZ available, but it never really caught on over a wide spread scale. The Savage 10ML-II. Its a real gun, built on a real rifle action. You could shoot black powder out of it if you wanted. But all the real advantages came with shooting smokless. I’m glad I have mine, and haven’t had the black powder out of the safe for years. I shoot 43gr of Vitavourhi N110 behind a 300gr Hornady SST. I’m comfortable out to 200yds with it as that’s as far as I have practiced. Alas, they stopped production because of demand. And now a used one commands 2x what the gun cost new.
As far as black powder guns go, I have a Traditions Pursuit Pro. After a trigger job, I loved the gun. It was a 200yd gun with 100gr of 777Magnum and a 300gr Hornady SST. However, if I ever dig it back out of the safe, it will be loaded with BlackHorn 209 as recommended above. I don’t know many hardcore MZ shooters that aren’t shooting BlackHorn now. It’s more consistent since its a loose powder, and is much easier to clean up. Everyone I can think of off the top of my head who has tried it, ended up switching to it.
If I was buying a new MZ, I don’t know that I would spend the extra money for the T/C name. They do make good guns. But I don’t know if I could justify the extra cost when there are others that perform just as well.
