New To Reloading Question

[PeteS]

Odds are rather slim that the factory load is using a powder that is identical to anything you or I have access to. One more propellant you may find both speed & accuracy from may be the power pro 2000.

As a new reloader I am guessing Case trimming & annealing  may be  areas you will wish to research & master.

Thanks, I know I probably won't match powder, I guess I mean the measurements of the case, like length and overall finished load length. Also the shoulder size off a factory case to set up my dies more than the powder. I'll try a bunch of different powders though.
