@Blind Squirrel I am using your daughter’s video for the example- nothing personal.
For all the people that are claiming 243win, 6.5cm, 7mm-08, etc “don’t recoil”- you are clueless.
This is a 243.  Look at the head movement and gun movement.
This is where her head starts right before recoil-

The difference in head movement between start and stop-

That’s a 6-8 inch snap of the head in an extremely short time frame- that’s getting into TBI levels.
 10 ft-lbs of recoil for an 80lb person is akin to a 338 RUM for a normal adult male, and when you factor the massive difference in muscle mass, especially in the neck and shoulders to hold the head still- it is a huge level of recoil to the brain.
Yes we all learned as a kid on 12ga and 300 win mags- I certainly did.  It doesn’t mean it was right, and it doesn’t mean it didn’t cause damage.
