i have reloaded tens of thousands of pistol rounds but only optimizing reliability, never loading for accuracy like i do in rifles, but now i am having trouble keeping 8" groups at 25 yards with a production pistol. I've tried three different bullets (125g LSWC and 124g plated RN and some mystery 115g JHP) with similar results.
my BEST 3 shot group of the day was roughly 6" at 25y shooting off a bench with the gun rested on a bag!
i'm thinking 80% chance i just have a crappy barrel/gun vs 20% chance i could fix this by changing my load. i'm not willing to change bullet or powder type, only the charge weight. brass is mixed, fired
Sooooo....in your experience tuning handloads in a pistol, what's been the largest variation? e.g. "x grains of powder gave me a y-inch group and changing to z grains of powder improved that to ..."
