I've been using a JM930 since the middle of last year, and finally got it fit right and feeding 100% over the winter. I had my first 3gun match of the season last weekend, and save for the times where I knew I was obviously messing up (misses, fumbled reloads, etc.), I felt like I was finally getting a feel for the shotgun as a system that I could "run", instead of just a boomstick.
My issue is that during long horizontal strings of clays or KO plates, the recoil of the gun is pushing mostly straight back (good!), the vertical rise and drop of the bead is controllable and consistent (good!), but after about the third shot in a string, there is a point where if I shoot any faster than something like a ~.3 split between targets, my entire body is getting shoved around and rotating about a vertical axis(booo!). Trying to stiffen my upper body to fight the rotation just pushes me straight back to the point that the SO is ready to catch me, thinking I may actually topple over (I'm not). Plus, fighting the rotation basically counters the movement I use to clear the string of clays/plates and slows me way down.
Additionally, I had a stage where there were 10 KO steels that had to be engaged from under a barrier. I'm right handed and went down to my left side. Having the shotgun shoot from my raised shoulder definitely rocked me over towards my back so I had to corkscrew my sight picture back onto the plates as I rolled forward. I know it was the same for other shooters, but I really felt I was doing something wrong with recoil management.
Does anyone have any tips or drills for improving splits? Most people at the match said it was because I'm not that top heavy. I'm 155lbs, (maybe 5lbs more lean mass in the middle of summer), shooting federal #8 target loads.
Looking at Lena Miculeck, in these vids:

I know it has to be something else. I'm assuming she's not 200+ lbs and her splits are where I want mine to be. If I tried to engage those clays at the same speed, my shoulder would be a foot further back from where it started by the third clay. She looks like she has a more bladed stance to begin with- I start pretty square to the target and handle my shotgun like I do my rifle.
I sense that I'm getting the recoil pulse back at the exact same time I'm trying to "reset" my eyes and body for the next shot, instead of feeling the "shot break/recoil then eyes to target" like I think I do with pistol shooting. Thus, by the time my eyes are on target for the next shot, my body is still in the process of coming back to it's neutral position and is getting stopped by the recoil of the next shot. I might be totally wrong though.
Tips? Tricks? Drills?
Thanks!
