I’ll do some dry firing and try getting more in line. I use to think I was a decent shooter because I can hammer with my 6.5 Creedmoor (consistent 1/2 MOA groups which is good for me) but I guess the extra recoil is probably exploiting a lot of my flaws like has already been pointed out.
If you want to figure out if you're subconsciously flinching or doing anything subtle or that you don't recognize... You already have a smartphone with a camera, so get a small tabletop tripod, a phone holder, and record yourself dry-firing. Watch the video, see if you're doing something off, and then consciously correct it. The best way to figure it out, is to record yourself at the range. Put the camera at an angle to your right or left (depending on your shooting hand), up around mid-barrel length of your rifle, and point the camera at you, where you can see your head, your eyes, your face, your hands, and your trigger finger. Watch later for subtle movements or nerves or flinching or target panic, trigger-slap, etc... It's a cheap and easy way to help correct your basic shooting fundamentals.
I have several of these tripods and they are VERY sturdy... You can use them for a number of things, like a Garmin XERO chronograph, testing optics, mounting your spotting scope, etc... So, it's not just a 1-trick pony purchase.

And get a good metal adjustable phone holder like this. Worth every penny... I use one of these for recording my videos for years, and it's a solid unit. Will last a lifetime if you take care of it.
