Bipod vs Bag POI shift

PerkyVal. Yeah I notice a difference with my Impact as well. I have the Atlas bipod and I think it's worse when the bipod legs are straight down instead of pointing forward. It feels to me like when using the bipod the gun can sort of rock back when firing, making the POI a little higher. I try to zero it in the prone position, then if there are any longer shot when out hunting I make sure to use the same position.

If I am shooting for X’s this is the bipod I used in F class shooting for years very stable, The regular Bipods tend to be unstable no matter what the price. I use a bag when shooting several different rifles on the range.

Pictures didn’t go through. I’ll work on that.

i like the atlas bipod and rear bag i get good results with them,I also keep the legs forward.

3rd try? Bipod

"Cheating bastids" LMAO!

If you have a pretty stout bipod, tilting the legs forward is basically the same as moving your bipod attachment point closer to the muzzle. The closer to the muzzle you get, the steadier the rifle can be held.

I have noticed this with a lot of guns and the Impact is worse then some. My general guess from lots of trial and error is that its a mix of specific gun recoil (like springers being more hold sensitive) and also your change of hold between the two different shooting styles. 



I find what works best for me is to tune a gun using the most solid setup you have. Once you know the gun is shooting at its tops now it's time for me, the shooter, to learn a consistent hold technique that will work for my general shooting condition. For me that is pesting at farms which includes a lot of out of truck window goofy holds, bipod on hood or roof(Atlas brand), and occasionally a tripod shooting stick. So I start shooting targets with as loose of a hold as possible which seems to duplicate the quick shots taken in above mentioned positions. Now you adjust your POI to the new style. 



I actually do almost all my practice at a bench in this same manner to improve my technique after I know the gun shoots well.

When you attach your front rest to the guns frame/chassis it's not a suprise that it will shift between a bipod used and bags.

If it were a stocked action the shift would be far less if not noticeable at all.

If you want to see a truly dramatic difference, try the same experiment with a magnum springer
