I'm just curious if you guys have favored loads for each specific caliber and firearm or if your goal is one load that functions well with good accuracy in all your handguns of a given caliber. I basically work up one load for five different 9mm's from a couple of M&Ps, a HK VP9 a G34 and a 92FS and when I find one that runs well in all of them and shoots as well as I do I build a bunch of them. Is it worth tweaking the load for each individual firearms? I keep it simple and load mostly FMJ or plated RN and haven't tried self defense rounds because I tend to buy factory ammo for carry. Just wondering?
