Hi All,
Can someone let me know what the max width is for an FTR bipod?
Had a bit of a look(I can only do a man look).
Also does anyone do them with an offset to counter torque effect?

it would be great if someone can help Tim find an offset, torque countering bipod, coz then he would hopefully be shooting FT/R and not be in F Open taking Queens badges off poor deserving old fellas

If Sinclair had have thought it out just a tad more.......

Someone correct me if I'm wrong, (nicely)
I thought total weight was the main factor to be worried about in FTR. 8.25 Kgs which includes Rifle, scope & Bipod. Use whatever you fancy on your rifle as long as it's under the weight rule. Plus a few rules regarding the bipod feet and bag permitted.
Any weight projectiles in .223 or .308.

As far as I know these are still the rules : http://www.icfra.co.uk/FCRules_2009.pdf

Regarding bipod width, there is no specified limit, and probably should be. But common sense would say that it couldn't be wide enough to cause space problems on the mound.

For anyone interested look at :

For any queries or question you may have ref: rules or dimensions

FTR for bi pods have no width restrictions but look at
Rule F2.2
Rule F 2.3
Rule F2.16
Rule F2.20.1

Now thanks to the S & T & NRAA for inclusion in the SSR's members should print off these rules and have them with them at ranges and displayed in club houses
knowledge is good

How would an offset bipod counteract torque?

Hi Tom,
If the rifle torques anticlockwise and is offset to right(as you shoot)this increases the distance to the left foot on the bipod from the barrel which will make it lift more than twist. That's the best I can explain it.

Tom,

If a rifle is clamped firmly onto a bipod, the torque recoil will tend to tip the rifle and bipod over to the left. This can be reduced by having the bipod offset to the left. But its not all good, because the rifle will then tend to buck more vertically. So to counteract that you could move the bipod back a little etc. etc.

I'm unaware of Krieger twisting their barrels the opposite way to the rest of the world - correct me if I'm wrong about this - but my rifle jumps vigorously to the right. Or is that because I'M left handed?

I thought mine did too......I am another Leftie.......till someone told me to go and have a close look at the front bag on my SEB Neo.
Now I know that it was bouncing to the RIGHT.....just after it bounced really vigorously to the left.
I now have to redistribute the sand (ie squeeze the front bag) before I shoot each string, coz with the 284 Win it get quite a marked depression on the left hand side after just 10-12 shots.

I'm sure they torque anti clockwise after which they land to the right compressing that side of the bag.

Hey Tony should have read your post more closely, there I go with my man look again

Barry,

The initial torque effect will be anti-clockwise I'm sure. This happens very quickly, and what we often see is the rifle bouncing back, and the direction of jump can be due to other factors. Would be interesting to get a slow motion video to confirm. I can tell you that every offset BR stock I have seen has the fore-end widened to the left.

The effect of torque is very very small --almost nothing. The recoil effect is however very large. What torque effect there is is to the left in a right hand spin barrel ( reaction )
What one thinks is torque effect is actually recoil effect, and may cause the rifle to jump either right or left depending upon outside influences.
An offset bipod will not counter recoil effects. A wider footprint will certainly help stability.
The recoil effect is only felt after the bullet has exited.
