Re: First time ML owner!
The beautiful thing about mz's is the fact there is a myriad of options for one gun as to the loads and load develpement.
In that dept they are much like a rifle as to what bullet, powder and primers they prefer.
With that in mind the best thing to do is get a load book specifically for mz's and follow those directions.
You are gonna need to decide what powder you wanna use....black, pyro or some of the others......just not smokeless unless that particular mz is made for it.
(I think the only factory I can think of at this moment is Savage 10 ML)
Also bullets what do you wanna shoot? conicals? Round balls? Sabots? there are a ton of em out there.
Primers to me is the least I would worry about, bullets being first, powder second.
Hope this helps.
