Bipods and Zero

I just recently got into hunting with a rifle. In antipation of my hunt, I spent lots of time at the range - first zeroing from the bench and then practicing with the bipod that I planned to used.

When I used the bipod my zero was different. I chalked it up to not sighting it in properly from the bench, but I just read an article today by Craig Boddington in which he said the bipod will change the zero.

My question is why? Shouldn't zero be the same regardless if the rifle is supported by sand bags or a bipod? Doesn't make sense to me, but I experienced and Boddington said it so it must be true - right? Wrong?

Unlike sandbags, bipods change the weight of your rifle and therefore the way it recoils. This will change the POI on your rifle. As well, depending on the bipod, you could be putting pressure on the forestock during firing that will also affect POI.

Bipods and Zero

Where I live Bi Pods are a waste of time.

How many people are going to lay down in the snow to shoot at a deer when it is running through the woods.

Especially when it is 5* outside.

I use a mititary sling, not a bi-pod. But from what I understand, nothing more than the ground ths thing is resting on can change the point if impact. If you think about it, the bi-pod becomes a part of the rifle. Shoot a rifle off a sandbag rest and a harder rest and the point of impact will change. The rifle recoil's away from the harder rest more violently. What I have heard is to try and rest the bi-pod on loose ground. The harder the ground, the more violent the recoil away from it. Don't know but that come's from a good source.????

Just wondering, does the rifle you are using the bipod on have a free floating barrel, a pressure bedded barrel, or full length bedding / fitted stock? The way a rifle recoils certainly has an effect on where it hits. My limited experience with bipods is mainly on a Kevlar stocked varmint rifle in 223 rem (low recoil) with a free floating barrel, and I haven't noticed any effect of the bipod on POI with this set up. I'll definitely keep this in mind if using something with a bit more punch.

Bipods and Zero

First please forgive me as I just woke up. Excellent points evryone. As most on the site know what I do for a living and I have a bunch of experence with by-pods on rifles. I have not seen an accuracy issue with free floated barrels namely the Rem PSS/LTR, Savage 10/110 L.E. , Winchester Bull barrel variants in kevlar, syn. stocks. Where I have noticed the change is wood stock factory guns and laminates with the pressure points (This also apply to using a tight sling). The easy fix is to free float and glass the action, then test it again. I generally keep a by-pod on for quick supported prone shooting but much prefer a ruck sack. Excellent point of no hard on hard contact with a by-pod. It''ll jump around like a fish out of water. Find a soft spot in the field/range and dig those rubber feet into the ground while pulling back into your shoulder. Best of luck to all, have fun and keep a hunting.
