Point of impact change from bipod to tipod?

[DocGlenn]

Just got my tripod back from Outdoorsmans with the rear-support installed.

Outdoorsmans Long range Rear Rifle Support

It seems to be a good option for situations when you can't get prone and I was able to make consistent hits at 300 yards (as far as I can shoot at home). However, my "consistent" hits were about 1-1.5 MOA low at 300 yds. I'm guessing it has to do with the different support. Anyone else ever have this happen and if so, how do you deal with it? I tried different shooting techniques off the tripod, but they all seemed to shoot low compared to a bipod/rear-bag setup. Any advise on this one? Thanks!

biggest thing to remember when you use shooting sticks or a tripod system is to keep them perpendicular to the rifle.

If you have them leaning forward or backward at all, they will rise or fall and make your impact high or low accordingly as you fire your rifle.

The most likely reason is that it's due to a change in your cheek weld and eye,sight alignment.

I think you're dead-on with that. Got to practice more and get the tripod shots to match up to my bipod shots. Thanks.

I would look at your form before I would look at the gun or the tri-pod.

I noticed the same thing shooting of the ground or a bench.

I agree, changing your cheek weld will cause vertical changes in impact. So will putting the butt plate higher or lower in your shoulder. So does the amount of vertical pressure under the stock's forend on its rest.

But I disagree with a change in eye, sight alignment. With a scope focused at target range, you eye can be anywhere in the exit pupil's cone of vision as long as the reticule's on target. People shooting benchrest rifles in free recoil don't touch the stock at all with their head; their eye moves around a bit relative to the scope's optical axis for each shot.

Great video. Don't think it can be explained or demonstrated much better than that. Thanks for posting.
