Shooting With a Bipod -- Question

Hi all,

I have just started shooting of a bipod at 900 yards today. I seem to bounce to the left after recovering from the recoil. What sort of things causes this. I have found holding the forearm of the rifle helps but I dont thing this is the answer to my problem. I use a rem700 police with a 10x leupold M4. BTW I hit 5 out of 8 on a 16x32 steel plate.

Thanks,
 
The movement to the left is the rifle's reaction to torque caused by the bullet accelerating down the barrel and gaining velocity and spin.

By "preloading" the bipod,pushing forward before the shot) you can eliminate some of this.

Weeeeell not quite...
...,that's the polite version, so I won't upset the "Mod").

I have spent a few days with a Guru in the mountains looking for my Karma... I found it! I shot it at 973.8639 yds, with a .264 WM Sendero-II-SF and a MK4-M3 scope!

Which way the rifle moves,jumps) on recoil is TOTALLY dependent on how the stock is positioned.

When I first started shooting prone with a bipod, I was instructed in the "proper" prone position,body ~ 45 degrees to the bore axis), and my rifle jumped to the right,maybe my spin and torque were confused, ya' thunk??).

When I started shooting timed field matches, and second shot time was critical,and cost me points to bring the rifle back on point), I started playing around with my position, and found that the direction of jump was totally dependent on the angle my body made with the stock, and how I held it.

I could make the rifle jump to the right or left, or drop right back were it was when the first shot was fired...

I have found that with myself, when my body is almost in a straight line with the barrel, the rifle drops back where it was.

Well Well, look who's back. We were starting to miss your humor and scathing comments. I am glad you found your Karma. By the way it wasn't Brokeback Mtn. was it HAHaHA!!!!!!!!!!!

Welcome back you crusty old Bas----.

Well, actually, aside from being ticked at some turkey named Kent, I was real busy this past few days. I moved my 16 yo son out of his mothers house,she is a child abuser), and we are filing for emancipation on Thursday, and he is done with her.

Suggest you read the article "Bugholes from Bipod" authored by Froggy.

http://www.6mmbr.com/TacticalFroggyA1.html

This guy is good... very very good. I've witnessed his shooting myself.

And I can say that Froggy's technique of pre-loading the bipod legs,by pushing forward) is a valuable technique. It takes "slop" or slack out of the whole bipod/rifle/body system, which works with a hard hold technique. For most folks, it helps control recoil a bit as you are solidly in contact with the buttstock. It also allows you to apply a little down-force to the whole system which seems to reduce vertical hop. With thumb on tang and a firm cheekweld you can get some downforce on the rifle.

Froggy writes: "When shooting with a bipod it is essential that the bipod be adjusted properly for elevation and cant. The bipod must be of good quality. I like Harris swivel bipods with notched legs. When the bipod is set up properly, and if you push slightly forward with the rifle to firm up the 'pod's legs, excellent results can be realized with lots of practice."

CatShooter has explained how he found that body position can effect stock hop/rotation. Interesting observation and definitely worth noting!

But there isn't necessarily ONE best technique. And the statement: "Which way the rifle moves,jumps) on recoil is TOTALLY dependent on how the stock is positioned" needs qualification.

What is the caliber?
Does the gun have a muzzle brake or suppressor?
Is the rifle nose heavy or butt-heavy?
Is the gun balanced around the rotational axis, or is it,whether accidentally or deliberately) heavier on one side than the other?

Watch this video: http://www.youtube.com/watch?v=CgVVyRrMLkk

In it you'll see Zak Smith shooting a 6.5x47 with suppressor. He lines up at an angle to the gun,not straight back) and applies a small amount of "push" or preload to the,rather wobbly) AI bipod, plus firm down-pressure with his cheek. Notice that the recoil is straight back--no hop, no torque.

But the way Zack shoots his suppressed 6.5x47 might not work as well with a big boomer. Here's a video of Terje from Norway shooting an Un-braked .338 Lapua Magnum. Note how the gun moves back and upwards pretty dramatically:

I have shot a variety of calibers from bipod, ranging from a 22LR to a 50 BMG. The bipod systems ranged in weight from about a pound to close to 10 pounds. How the rifle behaved after the shot broke, in my experience, depended on a variety of factors, including the bipod height/weight/leg-span, type of surface,and whether a pad was under the legs), presence/absence of muzzle brake, barrel contour, gun mass and center of gravity, and of course, caliber and twist rate.

I think a bipod shooter needs to try different things. Some shooters, for example, will wrap their non-trigger hand over the top of the comb or even use their off-hand to push down on the forearm.

Each shooter should experiment with various positions that suit his caliber, bipod type, stock, and physical frame. Some shooters, for various reasons, simply can't get comfortable with a straight back position. A 6BR is going to recoil differently than a .338 Lapua. A 6'5" 250-pound shooter will have a different experience than a 5'2" 110-lb junior shooter.

The best method for a narrow wheelbase bipod on a 10-lb rifle on hard ground may be different than the ideal technique for an 18-lb F-TR Class gun set up on a low-profile 20" wide Ski-type bipod on soft ground.

Mod...

I own a 50BMG and I use two bipods on it - a M-14 for down sloping ground, and a Parker Hale with a spigot adapter for flat land... the gun goes straight back,no matter what you do ;) )
