I tamed recoil anticipation by buying a 9mm.
Very helpful suggestions.
Also practice, practice, practice.
“Dry fire reveals a lot, but it doesn’t fully replicate the pressure of recoil. That’s where ball-and-dummy drills come in. Have someone else load your magazine randomly with live rounds and snap caps (dummy rounds).
When you hit a dummy round, the gun won’t fire—and if your muzzle dips or twitches, your flinch will be exposed instantly. It’s a humbling drill, but it builds real awareness.”
This is what helped me many years ago after I purchased my Beretta. I hit the range with it and incorrectly thought I would be punching holes in the center of the targets. That didn’t happen.
The range I went to has a few instructors and one of them was in a class with another shooter going through the same drill. He stopped my for a few moments, explained what he saw and what he thought it was and placed a box of snap caps on the bench in front of me.
He explained how I could use them to fix the flinch and also to simulate ammo failure. He said, “Pay for these on your way out.” then stepped back to his paying student. He was with me for about two minutes while his student was reloading magazines.
I did what he suggested and sure enough I was pushing the weapon. I made the conscious effort to correct it with the snap caps and made improvements that day. Following days were better.
This is worth saying again:
PRACTICE. PRACTICE. PRACTICE.
As a hunter I taught myself to ignore any recoil anticipation and make the shot count, nothing is more important than taking the animal cleanly and quickly, you can deal with the sore shoulder or hand later. 
It really is mind over matter, or if you are flinching that bad get a different handgun/rifle/shotgun/caliber.
I’ve read some instructors have their students close their eyes after lining up their shot, such that they get a better “feel” for the recoil. This helps to overcome and control any “recoil anticipation” anxiety.
Ive done it a few different ways especially for new shooters.
For the 30-06 I had, loaded cast bullets down to around 800fps, felt like a 22 mag. But for new shooters, it helped them work their way up to factory. They learn how to work a bolt action and work on the basics without full recoil.
Teaching folks how to shoot an AR, I load the mags and occasionally a spent piece of brass found its way in the mag. Real easy to show them how they jerk and very effective in the new shooter to understand what I was trying to tell them. I started doing that when I was a RSO in the military when I would see a young Marine having a hard time on the range
Or if someone complained about recoil but yet they had to have the 338winmags, 300wimpy, etc id let them shoot my 458Lott. 8.5lb rifle with a 18"bbl pushing a 500gr solid at 1800fps or so, they shut up about recoil on the mid size calibers.
It was kinda fun
Im not to keen on closing the eyes. I want them to see what they are shooting at. I always worked more on breathing and slowly squeezing the trigger. I wanted the recoil to surprise them.
Tried to teach them when they are exhaling, the trigger should trip on the target. One problem I seen alot is people would hold there breath for to long and then the wobble would come and they would jerk it just to send it.
Imo, the biggest part of handling recoil is the shooters form. After they get that down, then if the gun is a good fit. For rifles, the stock fit is a very big deal.
Kinda like an ex-brother-in-law of mine when he borrowed my .303 to go hunting because his .270 was “in the shop.” He dislocated his shoulder, fell out of the tree stand trying to climb out with one good arm and broke three ribs when he landed. He dropped the deer but had to leave it there.
When I am target shooting with a longarm, I typically shoot at the bottom of the exhale. I take a deep breath, let the air escape without forcing the air out and fire when my lungs are static. I find that is where I am the most stable.
Thats what i was trying to say, unfortunately alot of new shooters hold it to long and the barrel starts moving. They gotta learn that after a few seconds to take a shot or start the process over.
I also told them that when they get done exhaling (worded better) close their eyes and then open them. If they aren’t on target, they have bad form and to readjust.
Start with the basics and generally recoil wont be an issue….until you get into 40+ cal
Not to mention the gun. My wifes interarms MKX is beautiful, but she’s 5 foot and the stock was to big. She shot much better after we cut it down for her. My 458lott had a custom made Kevlar stock with a 10 Oz mercury recoil reducer. It was made for me. Alot of folks go out and buy the super dooper magnum and have issues. Could easily be fixed by spending a few bucks on a new stock.
Weatherby stocks for some reason dont fit my style, those rifles will knock the snot out of me. Its just the way it goes
