I thought I had the most accurate hold for my .177 Diana RWS 350 Magnum, which is the hardest recoiling and one of the most powerful spring-piston air rifles in my collection. Its recoil makes it one of the hardest rifles to shoot accurately.
The intrinsic (mechanical) accuracy of the rifle system does not change with manner the rifle is held in. However, the grip the shooter exerts on the rifle does influence the dynamics of the shot cycle. That is, when the piston/spring/pellet/barrel (vibration) are in motion.
Springers are so darned temperamental another gun might like position two, etc. It would also be nice to see that repeated with two or three additional shooters. He didn't mention his trigger hand grip, thumb position or how tightly he holds the gun.
I can change the POI and group size my 34 shoots just by changing my trigger hand thumb position. Hold too tight with the trigger hand and the groups open up. Too tight in the forward grip and groups open. And a variation in cheek pressure causes similar effects. And all this shooting a 34 not a 350 mag. This is partly why I'm heading toward the milder, easier to shoot springers.

Check-Out the Video at Approximately 2:42min ... Firing Hand Detailed

RedFeather, if you view the video at approximately 2:42min the position of the firing hand is detailed. However nothing is mentioned about thumb placement. Other than what you can see in the video.
As long-time readers of this blog know, the trick to wringing out the utmost accuracy from a spring-piston rifle is to use the artillery hold that B.B. Pelletier has popularized. It allows the rifle to recoil as it wants, while achieving consistency in the point of impact. In the artillery hold, the forearm of the rifle rests lightly on your palm or the back of your fingers or top of your closed fist so the rifle can move how it wants. You do not grasp the forearm with your fingers. That technique is explained here.
I did not see a link to a video in the blog. Anyway, his tests were interesting but nothing really new. Finding the most accurate hold is something done for every gun. Many competitive shooters mark positions on the stock for holding and resting so that the gun is held exactly the same from shot to shot. Personally, if you want to reproduce this shooter's test with your own gun, I would suggest blue painter's masking tape tape over what looked to be electrical. The glue on black tape is murder in hot weather. Cheers!
