Hi!
I did a ladder test yesterday (25-yds, sandbags, 9mm 115gr Barnes, Tanfoglio Witness Match) with new-to-me Alliant Sport Pistol powder.
My best group was with 3.8 grains. I'd like to go lighter to see if they tighten up any, but am finding it tough to find data online.
Do any of you have a reliable minimum charge for this powder/bullet weight? Thanks~!
