I am just getting everything together to reload 9mm. Supplies are limited at this time and the powder I found is Vihtavuori 3N37, 115gr LRN and CCI small pistol primers. I am having trouble finding the charge for the powder. The only thing I am finding is for FMJ and plated. would it be a problem to use that charge with the LRN's? I am thinking I will need to use 6gr of Vihtavuori 3N37 to start with. I am still waiting on the primers and powder which may be 3 weeks out.
