I just got the harris for prone/benchrest, for my .222 Contender Carbine. When I shoot off of my plain old home made plywood bipod this rifle is a sub .50 MOA gun. With the bipod attached I get vertical stringing and windage is off as well. I epoxied the front swivel stud into the forearm and the bipod attaches rock-solid so there is no movement other than the normal flexion of the legs with recoil. I normaly shoot with a bag loosely filled of rice under the buttstock. I was excited over this gadget beacuse it would mean one less thing to carry while woodchuck hunting. Anyone experienced a similar problem?

Hi Scott:

Don't have any experience with a Contender, but my Ruger won't shoot off a bench with a bipod unless I put something under the legs to cushion them from the "bounce effect" off the bench. Even something like a few layers of shirt or jacket will do. If you want to shoot from the bench often, maybe a strip of dense packing foam or the like would work. Give it a try and let me/us know what happens.

I have to concur with the comment on forend pressure. While I don't experience the stringing that you do, there is a distinct difference in point of impact when shooting off the bags. Some say attachment to a barrel band stud is better. Someone had a custom forend screw/stud made and reported that it solved the forearm pressure issue. I also have an issue with the bounce experienced with the harris. I have wondered if it is not the result of the spring tension that keeps the legs in place. I think that on recoil the legs are kicked and they "spring back" causing the jump. I wonger if some sort of locking system would eliminate this.

BiPod Problems

Hello Lakota,

I certainly agree with KN, your barrel should at least be free-floated. You can use washers, pillar-bedding, a hangar-bar, or even PVC tape - but use something! Also, if you have a wooden forend that is a longer than normal (somewhere in excess of 8-9 inches), the wooden forend might be introducing some harmonics into the equation that you don't really want - you may also want to consider a laminated hangar-bar forend (preferably glassed-in) with a sling swivel stud for more rigidity but this is not mandatory.

I have seen the following be a problem (because I'm the one who did it!). When installing a sling swivel stud, don't remove any more wood than necessary - keep as much forend wood thickness as you can between the external portion of the stud and the nut holding it on from the inside, this can be critical I found out. I removed too much wood on one of my installations, and had to glass-in the nut itself and fill the hole with Marine-Tex to keep the stud from moving slightly (forward) during recoil. Once it was glassed-in, the rigidity and associated accuracy returned, but of course I probably won't get the stud out without some high-explosive of some sort!

I hope this information is helpful.

Good and safe shooting to you! :D

Thanks everyone for your suggestion. I am going to hang on to the bi pod and I will play with the bedding during the off season.
