Is There A Bi-Pod I Can Use As A Jackstand???

Re: Is There A Bi-Pod I Can Use As A Jackstand???

-Under Slung Trunnion and Pivot Point for full Rotation
-Adjusts to any Terrain keeping the Weapon Vertical and Level
-Low Center of Gravity resists the forces of Bullet Rotation
-**Now available in a Half Trunnion Model for even the most demanding Long Range Enthusiast

Now that all SOUNDS good, and I am pretty sure it is a solid piece of equipment, but can someone explain the 3rd one down to me?

Low center of gravity resists the forces of bullet rotation?
Never knew I was experiencing forces of bullet rotation on my bipods.

Along the same lines as wanting a toothpick you can hit a homerun with. Maybe bigger and cooler than the next guys, but its not really needed. Atleast I dont need one.

Sounds like bad cases of bipod envy here??

Every rifle has the forces of bullet rotation acting on it when fired. A rifled firearm will torque as the bullet is being pushed down the barrel on the same plane as the rifling. This is hardly noticable but it is there, so the statement may be true but...

Hey guys, check out this post I did on some of the big bipods. I use the LRA bipods on almost all of my rifles now. They are available is smaller sizes for the smaller rifles.

Rotational torque is a real affect that is more noticeable on larger rifles. The LRA does an incredible job of controlling this.

Well, the largest rifle I have is a surgeon built 338LM with an atlas bipod. I have never NOTICED rotational torque, not that it isn;t there, but unless I go to a 50, I think that is a rather large rifle. Granted it weighs in at over 18 pounds, so that might be a factor.
Will have to pay more attention when I shoot to see if I can detect the rotational torque. Generally trying to pay attention to keeping a sight picture after the shot. Am I looking for canting after the shot, or are we talking about enough torque to raise a leg up off the ground?

Thanks,

Re: Is There A Bi-Pod I Can Use As A Jackstand???

Rotational torque is generally found with bipods that have adjustable cant. You will find that the rifle has the tendency to roll counter clockwise. Having something that locks solid like the LRA allows you to have faster follow up shots and is easier to remain on target. You may not readily notice this movement unless you have a scope level as the motion tends to be small between shots. The RND bipod I tested on my Chey-Tac suffers from this rotational torque. There is a thumb screw on the side that allows you to adjust the cuff tension. I get it as tight as possible to prevent the rotation. After a string of shots you will find that the rifle has pivoted and is no longer level. This obviously plays a big roll in the ELR game.

This.


It looks nice, but too bulky. I'd run it on my .50, but it wouldn't be a my first choice for a rifle that I plan in carrying.
 
Re: Is There A Bi-Pod I Can Use As A Jackstand???

Until you've shot from one it would seem like a "ho hum.... that's nice for the cannons but not what I would want".

I spent a day shooting it on my 22" 6.5 Creedmoor. I own that one now, plus another one coming.

They're bigger than an Atlas or a Harris and they're more expensive but they're the most stable thing I've shot from short of a full BR front/rear setup. The big bipods on that website you see are the 50cal and HTI rifle setups. My F-class model is about 2/3 the size and 1/2 the weight. The latest one I have on order is about 3/4 again the size and lighter still.

My experience with rotational torque effect starts to appear with .338LM and larger calibers.

I can tell you that moderate .338LM 250gr loads out of my TRG42, if you loosen your firing hand grip it will torque the pistol grip right out of your hand upon firing. It's quite the surprise if you've never fired a .338 before. LOL
 
Re: Is There A Bi-Pod I Can Use As A Jackstand???

I think some of it might be due to the rifle being lower and sitting in the cradle of the bipod also. It may give some stability from torque. I know with my '06, it is fairly light, and when I fire it, it will jump up and left pretty hard. This is with meduim length harris, I haven't tried a short one, that may alleviate the effect somewhat. I think it would be a lot easier to shoot if it stayed down.
 
Re: Is There A Bi-Pod I Can Use As A Jackstand???

I bit the bullet and tried the LRA. It's the only one I'll buy from now on. The stability it provides is unbelievable. Yes it is expensive but it works better than anything else I've tried and that is most of them. To me it was worth every penny.

I will echo bohem stmt.

I have had the F/TR version on my 308 rifle for the last 4 months prior to that the Harris. Both the harris and atlas have the rifle sit on top of the bipod and the affects of recoil are more pronounced, both back and to the side. with the rifle sitting in a craddle (essentially) such as with the LRA, their bipod design helps reduce both of these effects. it is a great bipod.
