Bipods??
« on: April 27, 2009, 04:23:56 AM »
I'd like to see a discussion on these. I've heard this is a good one:

    Rick on airgunweb.com put one on an air rifle that wasn't grouping well, and said it really helped the accuracy of that gun. Anyone tried one of these, or any bipods? How did it work out? Is it worth a try on a springer that a person is having trouble getting consistant groups?

  Thanks, Jon

I use a bipod quite a bit. Not the same one - not even the same style or attachment method but I think some of my experience may help you.

Any bipod that attaches to the barrel, or to a flexible frame/stock to which the barrel is hard mounted has a side effect... direct upward pressure on the barrel... raising the POI compared to the barrel "at rest". This generally isn't an issue where the bipod is attached to a firm stock that supports the barrel.

Example - I've gotten to the point i can shoot sub 1inch groups, offhand, around the bull, 75% of the time at 10m with mt Talon SS. The Airforce rifles have a fairly beefy aluminum 'frame'/shround to which the barrel is hard mounted. The bipod also mounts to this frame/shroud. If I set up my table and shoot the same target off the bipod while allowing the bipod to cary the weight of the rifle, my groups CAN improve, but are higher just from that slight pressure producing some frame flex.  Point is, it can definitely help, but it can change expectation and/or magnify error. (think about the gun hopping a bit with the recoil... resting on a bipod is going to change the effect movement - just something to get used to)

That said, I'm definitely better with the bipod than I am with a bag or freestanding front support at distances beyond 10-12m but I had to learn how to use the bipod and how to hold the gun exactly the same way every time (without variation to verticle or horizontal twisting forces). The bipod won't make your GUN group better, but it will/can help you shoot it more consistently.

This is mine. (the foregrip has since been moved all the way back to the trigger gaurd and the bipod has been moved as far back as possible, so - about 8 inches further back than shown in the pic)

Thanks for the explanation JQR.  I've also noticed this from shooting in the GTA matches.....whether shooting off a bag rest, elbows propped up, prone, off-hand, mini-tripod or shooting sticks....the point of impact will be slightly different between them.
