Welcome.
I wont get into your question to much but you will get answers from those with much more know how than I
At this point being new and the season upon us,if pelletts are working well for you,use them.
They are easy to use.I find I get better accuracy with loose powder and I can taylor my charge to the bullett and primer I am using but I still use pelletts as well because I cleaned out the bargin bin at wally world.
There are so many variables that I will leave it at that.

What gun are you shooting will be one question you will get.
What type of game do you hunt and at what distance?
Will you be using your ML one week a year or will you be shooting allot?
