Bench shooting vs Bipod

I have a small range next to the house, with a bench and a lead sled. You can shoot very well on the sled. I put on a bi pod and started to shoot with it instead, I noticed that at 500 yds I was 6" low at 600 yds I was 10" low and at 700 yds I was 15" low. Sand bags was few inches better across the board. I tried the other 2 guns and give a inch or two they shot the same way. The calibers used were 6.5x284 7 mag and 300 win mag. This all started because a few weeks back I was using the 6.5 on a doe hunt, I got one at 411 and another at 565, I missed at 735 yds, both does were hit very low so I had to see what was going on. I had no idea that there is that much difference between a bi pod and a bench. Has any one else experienced this ?

Re: Bench shooting vs Bipod

I am not a super experience long ranger by any means, but somewhere I read about this so from now on I always do everything with a bipod and rear bag as I would do it in the field. That way I know I can carry it over I guess. If anything it is a confidence thing maybe, who knows. The more experienced guys will be able to help you out on this more than me though.

Re: Bench shooting vs Bipod

Google on "bug holes from bipods"

I don't use flex legged bipods thus don't concern myself with "loading" . . .as much.

Shooting bench with pedestal rest, sand bags or bipod up front with rear sand bag all equal same POI.

Prone with pedestal, sand bag or bipod up front with rear sand bag = same POI as above.

Re: Bench shooting vs Bipod

I have seen and heard people shoot low from the pod as well. It has to do with PRONE vs sitting and the angle of the face/eye to the bore line of the scope. Many of the experts who shoot bench and yet hunt will rezero from the prone if they have issues with POI from the different positions. Every "body" is different so I think for you it might need to adjust how you shoot prone or zero for prone/hunting situations.

If at all possible identify what you do differently that makes you shoot low and correct that so you are consistent from each position. There are couple of vids out that address, Gunwerks has one I beleive. I think the shooter was .25moa in the vid. Not bad for bench to prone shooter positions.

Re: Bench shooting vs Bipod

I believe it's all in your shooting style. My POI doesnt' shift from the bench with my FarleyII with a joystick with a 20lbs protektor bag, to my Sinclair tactical bipod with my 3lbs rear bag off my shooting table. BUT it took me a long time and a lot of trigger time to develop a style that would do that. laying down and shooting prone it shifts as the stock is hitting my shoulder differently so the recoil is different and shifts the POI.

I might have read this wrong but I think you are saying your POI changes bench to prone as well.

I have a raised cheek piece I built for my rifle to keep my eye more aligned consistent with the bore of the scope. This helps me keep my zero point whether prone or seated the same. For example I generally shoot 1000 to 1500 and do it prone, but occasionally I drag the table up the mountain or shoot off the 4 wheeler or seated if I have to deal with brush. My MOA adjustment from 1000 to 1660 has remained the same in seated and prone positions. My method is that I just try and put my cheek on the pad the same, shadow the scope the same, and shoulder the butt the same. Early on I scoped myself due to improper form and quickly looked for a better solution to this low profile angled head and eye position.

I cannot speak to the prone really as I don't do it. I shoot from fixed benches or table. or flipped down tailgate and a stool lol.
I am not a brush beating hunter If I take the long range gun it's with my table. I am sure that my POI would change if I tried prone, but don't know if it would be from the change in eye allignment or from how the gun is ridding on my shoulder VS how it's sitting on my arm when I am on the bench/table.
