Yesterday I recommended a powder to a shooter who was inquiring about a good load for a 12 twist barrel. I quickly started typing and meant to recommend Vhit N133 which is a find powder bullets a 12 twist barrel will let you use. What I actually typed by mistake was N150. PLEASE BE CAREFUL WHEN RECOMMENDING LOAD INFORMATION TO FELLOW SHOOTERS. We would hate for someone to injure themselves or worse. To the original poster, thank you for seeing my typo and not trying N150 with a 53 grain bullet.
