How long did it take you to find the right 9mm load for your gun ... USPSA match
Not long. I started reloading because I started shooting USPSA matches with factory ammo and other match shooters told me I need to reload to reduce my group size.
I did my initial load development with Bullseye, Clays, WST, Titegroup, W231/HP-38, Universal, WSF, HS-6 and my average reload groups shrank best of factory groups by more than 40%.
If you can place all of your holes inside 1/4 piece of copy paper (which is smaller than "A" zone) at typical USPSA target distances of 7-15 yards, it is good enough and many loads with different powders meeting 130 minor power factor will achieve this.
Accuracy must be acceptable. This ain't bullseye. It is immaterial to your overall performance whether your gun/ammo groups 1.5" or 2.25" at 25 yards. It makes no difference.
Recoil and sight-tracking behavior is to your liking. USPSA is a speed-based game. Being able to manage recoil and tracking the sights is a big part of being able to shoot quickly
The whole game is points divided by time. More time is bad.
What ATLDave posted is very true.
While Bullseye/WST/Titegroup produced smaller groups, I preferred the slower "recoil impulse" from W231/HP-38 that allowed me to get back on the front sight/target for faster double taps. So even though W231/HP-38 loads were slightly less accurate (slightly larger group size), I was able to shoot the match stages faster. For USPSA, faster stage time will trump slightly greater accuracy and you will end up with higher stage score. Yes, this is one aspect of USPSA "game" but it's a rule we must follow to get higher stage scores.
Even Rob Leatham explains USPSA is a game of "scoring". Rob points out in this video "You have to be fast enough to matter" for competition shooting and "
Shooting accurately enough, faster is better than shooting extremely accurate, slow" and negates many myths about accuracy vs speed. And for USPSA scoring, that will always be the case -

Member 1KPerDay wanted to not only maintain accuracy but increase speed as well and we outlined step-by-steps and various match shooting techniques on this thread like this post of fundamental "double tap" for accuracy and speed -

And just as there are reloading variables, there are shooting variables too. Just to rule this out, dry fire while watching the front sight. If the front sight moves/jumps when the hammer/striker is released, you may be adding trigger/grip input and moving the muzzle of the barrel. If so, follow this post to eliminate that -
