This will probably sound crazy, but trust me it works!
Use a haris bipod and connect a 1 inch qd swivel to the sling strap hook on the bipod
to the 1 inch swivel run a 2 foot length of nylon webbing and attach it to a tent peg jammed into the ground in front of the rifle
You pull back on the rifle until you have good tension on the strap
At this point your wobble area should be zero with the butt settled into your rear bag - maintain cheek pressure as well as moderate rearward pressure
The strap tension will prevent muzzle jump and absorb recoil.
If your setup is clean you will be able to watch the vapor trail of your bullet as it flies to the target
Seriously, give it a try
What a novel idea!, gonna have to try.
Were you using a full caliber (6.5mm +) while seeing bullet trace?.
