I know this may be an adolesent question, unless you are new to reloading. Your input is appreciated. 9mm 115 gr RN FMJ 4.1 gr Win 231 Use: Skills practice on paper and steel Glock 17 4.1 is the starting load recommended by the new Hornady book for Win 231 and 115gr FMJ. I loaded 15 to test and was satisfied the accuracy and had no troubles that I know of. Seemed to operate the slide just fine. I threw in a factory target round in the middle of the mag just to see if I noticed a difference, I did not. Is it ok to be on the low end of the recommendation? Anything else I should consider?
