I will be using 9 mm . Yes, I am new to reloading actually just gettting everything together. If I can't get 320 would 330 be acceptable for both 124 and 147. I will be using them for IDPA and USPSA. Any advise would be appreciated. Thank you so much.
I have decided on N320 powder, but having a tuff time finding this powder. I will be using 124 gr. FMJ MG, is there a big difference between N310 and N320? If I can't find 320 can I use 310 with different amounts?
Thank you for your time.
