I’m scratching my head on how the form comes off after the pour.That form is awesome AND it looks like it's stainless.....
I'd rent that for a weekend, please....

As am I.....?I’m scratching my head on how the form comes off after the pour.
Don't forget Ed Eckhoff. (BTW, I paid for two of the benches to be poured/built way back when at the long range... And I wish I could still shoot there, but it's a long drive from Texas.)Looks identical to the design Bob Dorton & I used at Sac Valley. The ones we use for LR are poured tops in iron frames so they are movable (sort of) from 600 to 1000. The 20 we have for SR BR are solid poured in place on our 200 yd range.
Seems to be a popular/comfortable design for most shooters.

I have not discussed it with the builder, bu I would guess that there is a small taper in the base, and that some sort of coating is applied to the inside of the form after cleaning, before the pour.As am I.....?
I think the form come apart at strategic places in order to remove the form piece by piece. You then reassemble it for the next pour.I have not discussed it with the builder, bu I would guess that there is a small taper in the base, and that some sort of coating is applied to the inside of the form after cleaning, before the pour.
For me the question is whether the benches are poured upside down and the form lifted off, with the bench curing in that position and then flipped over, or poured right side up and then flipped for form removal.
Being a bit chicken about getting the form off, if I were to design one I would split the whole thing down the middle with generous draw in each half, but then I think that who ever built this form, looking at the bench, knew exactly what he was doing.
That is the form they use in Australia, you know below equator..I’m scratching my head on how the form comes off after the pour.
In the short range disciplines, group and score, barrels tend to be shorter than in the long range. A good deal of this is because of much lower weight limits. This limits how far one can place a rifle on the bench. (given the requirement for the muzzle to be in front of the bench)
Beyond that, unless one is a bag squeezer, until the advent of the coaxial rest, shooters needed to be able to reach the windage top to make adjustments while shooting. Some years back, I designed the top of a rather heavy four leg "portable" bench so that I could either shoot beside the rifle or behind it. For me beside was more comfortable.
Getting back to the windage top thing, I have a couple of McMillan Kestros stocks on rifles and they have significantly longer forends than my short range benchrest rifle. If I place the rest to take advantage of their long forends I cannot stay behind the scope while adjusting a conventional windage top, even when sitting beside the rifle. (even I take a 37" sleeve length)
Luckily I have a first design 21st Century rest that has the offset bag and the windage built into the base. With this setup I can utilize the longer forends. Otherwise I would have to have a coaxial rest.
On bench design, I think that it is often true that the fellows who have the construction experience and energy to build ranges and benches have not spent much time prototyping bench top shapes and they tend to just do a rough copy and build a whole firing line that will be there forever. In my conversations with people who were about to build one or more benches, I always have gotten the sense that they were not in the mood for anything that would delay the process.
I’m still too thick headed to see how that bottleneck under the top slips past the wider base, but probably looking at it wrong.That is the form they use in Australia, you know below equator..
It appears the form is tapered in all directions and when the concreate cures, bench is inverted and the form will slide off. Just guessing..
Ed was certainly the driving force behind the early success of LR BR at Sac Valley!Don't forget Ed Eckhoff. (BTW, I paid for two of the benches to be poured/built way back when at the long range... And I wish I could still shoot there, but it's a long drive from Texas.)
Still seeing a jam when that narrow portion of the form hits the wider pored concrete bottom portion when form is pulled up.Haha, maybe this will help? View attachment 1437218
I guess different people define square differently. Looking at his position the angle of his shoulders (the line through both shoulders as viewed from above) seems to be quite a bit more acute than square. His position is pretty typical. Here is a video shot as I walked behind the line during a match at Visalia, a number of years ago. It shows some variation in shooters positions, but in my experience they are pretty typical.Square to the gun for me. Behind it.
Darwin's "natural selection".But why, there has to be a reason.
I tend to agree with you, I don't think in the video Bart is sitting as square as he would like. But remember it's a video that he had to make. When I say square I mean 90 deg to the stock with my shoulder. Just the way I prefer. Could be it easier on my neck, leaning forward rather than sideways. I do have a plate in my neck.I guess different people define square differently.
