Re: Black Hills 175 MK Reloading
tsprink,
You are new to reloading, and that is great. Follow through with your ordering, and study up on how it all works, and why.
To start with, I'd suggest the Lyman reloading manual. It has the front half, which gives the description of each process and the 'how to do it' as well. The second half of the manual is their latest up-to-date version of the loads, with the latest bullets and powder configurations.
TAC being one of those powders. IMR is just one brand of powder, like Chevy, or Toyota. Each has MANY models, and that is what is being discussed on this thread. For a very specific load.
Hope that helps.
