My opinion (been known to be wrong) is that you should not hold the forearm down. I was told a long time ago that holding it down, or vicing it to sight it in is not good. It would seem to be really accurate but when you are hunting it is going to raise up and be way different then if it was held down at the range. If it is grouping bad at the range it's not because of the gun jumping while being shot. Reason I ever even thought about is was years ago a guy recommended I use gun vice to clamp the gun down and then it can be ready to hunt in 2 shots. I asked around and that's not the best way, maybe to get it close.
