No. It’s an angled stock, and an angled bag- it wants to move the rear end of the stock down during recoil.
Bottom line, if there is a miss high—outside of the natural wobble—it is because the rifle hasn’t been controlled during recoil. The amount of movement to miss that high is more than the rifle could slide during the instant of recoil.
Shooters who have good form can use no bag, a squishy bag, or wedge bag and not miss outside of their natural wobble. And they do it with angled stocks.
Case in point, the typical flat rectangular shooting bag that is held in the hand is still on the sloped stock, maybe a couple of inches. It is there to reduce the wobble zone. The shooter controls the rifle and keeps the buttstock from dropping in recoil.
As far as the wedge on wedge, if the stock is angled, the bag shape makes no difference. A square or round bag with fill ends up conforming to the angle.
The wedge is a tool designed to help mitigate the recoil, because it is hard to control a heavily recoiling rifle and many shooters haven’t had the instruction or training.
When the rifle is fully supported by any bag that doesn’t collapse, the amount that it moves as the stock goes down the slope is minimal. The wedge is designed to the stock, so it maximizes the shape for support. It doesn’t increase the slide down the angle any more than any other bag.
So, for the person deciding between the Wedge and another bag, if the misses are high on the Wedge, then the shooter has more recoil than the form they are using, the position they are in, or the body can control. And, switching to a different bag won’t help because it isn’t the bag itself.
The shooter who said he missed high with the wedge, seemed to acknowledge that pushing the rifle down into the bag presented the benefits and he got precision, which is what is expected.
Once there was play in the system, recoil exploited it. So, the shooter is right that switching to the lighter and non-wedge shaped bag won’t change.
It is something in the execution, and helping the shooter with form and technique will bring the improvement. It may be the overall shooter technique or how to use the wedge more effectively as a tool.
Anyone is free to reach out to me to talk about how to effectively use the Hunters Wedge or any other bag.
Having experimented a ton with bags, and improved/trained in improving my own technique, I can give a good perspective.
