Appreciate this thread is now somewhat old, but was this allowed under US F-TR rules? The “from the shoulder” words make me wonder…
I have a similar concept (very different manufacture, but similar underlying concept mixing up a few ideas from this and from the Jennings stock) which I’m making up. Over here we shoot under UK/ICFRA rules which don’t have the shoot from the shoulder wording, but I wonder whether the US rules will prevent me from shooting it in the US, when I come over…
TIA,
Andrew

I guess I forgot to add you have to go to the “F-Class” section first and then to 3.4 (a) (3)

So it should be:
Section 22
3.4 (a) (3)

Gabe:

Please recheck that link/citation – “3.4 Reduced Capacity Magazine”, just the one paragraph.

Boyd – I agree with just one barrel block. I see that Speedy is having good luck with a split block that lookings like a scope base with rings on either end.
The scope on this gun is an old scope that is new to me. It has tracking problems so I do not really trust it.
Tried some new powder and that isn’t working out. Back to Reloader 15 now so am starting load development over. Right now the 80.5 Berger are runing in the mid 4s at 2940 fps and the 90 Berger in the mid 3s at 2795 fps. I am getting 4 in a hole and a flyer(the flyer is included in group size).

How does it shoot? Also, I believe that if you tie a barreled action down in two places, as it heats up, and the barrel lengthens, stress with be created that will degrade accuracy. You can have it touch, and allow it to slide, but IMO if it is clamped or bolted in two places (the action and barrel for instance) the results will not be as good as if it is only restrained in one place (action or block).

Thanks Steve.
Jim – the rib was put there to stiffen the stock. It works.
Pat – I think the BR stock was made by CSC. McMillan has always been fiberglass. Yes I did follow (steal) some of the design from that stock but added the barrel block. This is like a BR rail gun without the bottom guide plate and a butt section added.
Gabe – I missed that rule. I will look it up. It will be hard to tell that I am not holding the gun.

I didn’t think free recoil was allowed in F class? Is it?

Richard – awesome work! I agree – the barrel-block system is the way forward where we have a sufficient weight allowance – i.e. F Class.

I’m using the Trueflite barrel-block stock for my next F Open build.

Your bi-pod looks worthy of an article in itself.

Excluding weight, is there any reason why no one uses any more than one mounting system?: ie
2 barrel blocks
1 longer barrel block
or even pillar bed action AND barrel block

each of these would increase the dampening provided wouldnt they? and wurely the mounting blocks could be skeletonised some also to shave weight. (drill/mill holes in the vertical plane?)

to my (very) basic knowledge these would all lessen the barrel whip/flex – a test gun with a straight barrel could simply have extra mounting wholes drill in the stock to enable moving the block forward backward or modifying block length.

if anyone in aus would build one similar to above (with grip and butt pad though) id love to try it.
