That is pretty cool. Is it available to people through a link somewhere in the forum list?
F-TR Class Bipod Recommendations?

I too like to keep weight about 17.75 with the scope caps on. Then I have a few ounces to remove just in case!

It's available thru the link there in the post. It's a Google Docs spreadsheet. Right now its 'mine', but anyone can view it using that link. If people actually start using it to where there's useful information then someone can talk to the forum admin about making it a sticky post or something.
It is amazing how fast you can shed some weight with a few little changes. Especially when you are talking ounces

What Im running, Tier One Evo carbon bipod. 19 and something oz.
Same bipod Im using, dont think ill be changing anytime soon.

Are these available from anyone here in the states?
The need to use weight to mitigate recoil is much more pronounced in .308 than in .223. I've seen lots of very accurate .223s well below 15 lbs and these also shoot well off of Harris bipods, because recoil management (straight rearward tracking) is so much less an issue.
In .308, a gun of the same weight moves more than twice as far as a .223 before the bullet leaves the barrel (other factors being equal), so using weight to mitigate recoil effects is more helpful. But not all weight is rigidly coupled to the barrel to have the same effect on where the barrel is pointing when the bullet leaves. The weight most rigidly coupled to the barrel is the barrel itself. In other words the effective mass is less than the actual mass because the barrel can't feel the effects of all the mass in the short bullet time in the barrel.
Then there is the issue of torque which really depends more on the rifle's moment of inertia about the bore axis than on the mass of the rifle. But things like the bipod legs are not as rigidly coupled as mass in the barrel itself. For 300-600 yards (where one need not maximize velocity) spending the same weight budget on a shorter, fatter barrel (higher moment of inertia) would be better than a longer, thinner barrel. But for these ranges, reducing recoil with a .223 would probably be the better plan (depending on the common wind conditions.)
Unless you are shooting a .308 at 1000 yards, trying to squeeze out the last couple ounces with a bipod selection is likely barking up the wrong tree.

I have been refining my weights and by making some changes in my components, I can have the new barrel, Vortex GE and a Dublin Bipod and still be under weight by 6.6oz. As you can see, I was heavy and by making some adjustments I would be well under weight.

See if you can get Kyle @ XLR to hollow out the bag bar on that Extreme butt stock. It's good that you included the folding adapter, cuz those buttstocks make it dang near impossible to clean the gun otherwise.
Personally I'm looking to make a different bag bar - one that is flat on the bottom with a slight taper, so it fits in the bag like an XIT does. I got one of Gary Eliseo's bag bars... close, but doesn't quite fit the XLR chassis.

I ordered mine from Tier One took about a week to get to Calif all so check http://www.ebay.com/itm/Tier-One-FT...193058?hash=item2a8488ef22:g:BlwAAOSw5cNYmPvM
Papa C, Im in South Africa so wont be much help but im sure you will be able to get one directly from Tier one. Very good customer service, also have a look at the Tier One rings while your busy
Yes, Tier-One supplies people around the world. Not just bipods, but top quality rails, mounts, unimounts and more.

There are two more super-wide UK made bipods, the Dolphin AB (another carbon fibre strut model)
http://www.dolphinguncompany.co.uk/bipods.html
and The Shooting Shed's 'Stotteben' model which is all-alloy, very light, and even wider than the Evo Carbon at getting on for 700mm at a low setting

Here is a review of the Evo Carbon being used in F-Open

Here is the list of F-Class BiPods that I have collected so far. Thanks to everyone for you help. If anyone has any others that they could recommend, please do.
Let me know if anyone would like to see more information on any of these in the list for comparison. I was thinking maybe adding some specs so it would be easier for people to compare.
