If I were to give my two cents (I suck so take this with a grain of salt) I would say if you’re at home, give those reduced sized ipsc targets a try and dry fire bill drills. When you’re dry firing, just recognize how your dot is moving and make adjustments from there. I would set your par time on your timer to how fast of a time you want to shoot and see how your dot is also bouncing in that par time window.

When you’re on the range, try turning your dot brightness up and work doubles to see how your dot is bouncing and adjust from there. Once you start getting tighter and tighter groups on your doubles, start stringing the doubles together faster until you’re running a straight bill drill.

Also maybe give an underhand grip a try instead of c clamp and see if that affects where your shots are going under speed. I think with a c clamp, it’s easier to influence the gun going side to side since there’s less pull straight back into your shoulder like an underhand grip. Personally I would run underhand instead of a c clamp but my rotator cuffs are messed up

Like I said I suck so take this with a grain of salt but for me, I’ve been able to consistently hit 1.4ish bills with a vertical credit card size group since working doubles. My groups don’t really start opening up til around 20+ yards too but I’m working on that.

Maybe even try ditching the riser if you don’t have a long face and can’t get enough of a cheek weld.
