There's a decent video with explanations at http://www.pyramydair.com/article/The_artillery_hold_June_2009/63
What all of that means is that the gun recoils as a result of the forward motion of the piston BEFORE the pellet even starts moving.
Clearly it's important to hold the gun consistently so that the motion of the recoil moves the gun consistently from shot to shot. Since it's nearly impossible to insure a perfectly consistent hold if you grip the gun like you would a normal firearm, the best approach is to minimize the shooter's interaction with the gun as much as possible.
Tom Gaylord's short article and video provided in the link in the post above mine have good information on the topic.
Thanks for that great vid on the artillery hold, now I can hopfully tame my springer and tighten up my groups.
That video offered a very good explanation
That is the same video as linked in post #3
Frankly, I find spring-piston air pistols that aren't recoil compensated/recoilless very difficult to shoot consistently. I've tried a variety of different techniques and none of them have worked well enough to satisfy me. I still do some shooting with a recoiling spring-piston air pistol, but primarily as training because it makes me work very hard to get even reasonably consistent results--not really so much because I find it fun.
I would think you'll have to experiment with your gun to determine what particular location works best. Maybe mount some kind of rail on the bottom of the stock that allows you to vary the position of the bipod until you find something that works.
You may have some issues getting a springer with a bipod to shoot accurately as the vibrations from the firing cycle can create some accuracy issues when the gun is rested on something hard--and a bipod would probably qualify.
But it doesn't end there. When the piston reaches the end of its travel, it faces a wall of compressed air that stops it FAST and due to the rebound characteristics of a spring, it actually springs back a bit causing a recoil in the forward direction as it bounces off the compressed air column. These are the motions that kill scopes that are not designed for air guns. That reverse motion is not designed into most scopes. Even some of the most expensive ones.
It becomes easier to see how important consistency is when shooting an air gun.
