I have been reloading 45acp for a while with great success with 5 gr wst. I have about 7 lbs of the powder but recently switched over to 9mm. Is anyone using WST in 9mm or should I invest in something different. I have loaded some blue bullets 147 FP with 3.6gr and seems to shoot pretty well. Had a few slide lock failures on final round. Wondering if I should bump it up or I will just have unburnt powder. I am a recreational shooter so do not worry about power factors. I like to keep reloads close to factory loads if it all possible. Thanks for the input. Sent from my SM-G935V using Tapatalk
