New guy here and 1st post. I just bought 4# of this powder and there isn't much data on it and none for 10mm. Looking for some mild loads for the 2x-3x fired brass using Berry's 180gr FP bullets. The published 40s&w loads are 4.5 -5 grs, thinking of starting at 5.2 but wonder what max would be on this? Gun is Gen4 G-20. I've used the ETR7 for 9mm target practice, very clean and groups nicely and plan on using for 38spl & 45acp. I have loaded 180gr Speer Gold Dots using Blue Dot and 800X in new Star Line brass and loving the 10mm. Thanks for any info and look forward to chatting with everyone!
