I'd agree with checking for copper fouling, especially if you had 1" groups and they disappeared. The copper will be pretty evident as streaks when looking from the muzzle unless carbon has layered over again. I've brought back a couple of barrels (SS & Cr-Mo) with Bore Tech Copper Remover and...

Again we come back to theory versus practice. In terms of what one shooter might observe at a particular outdoor range will not necessarily be the same at another range, let alone at a different target distance. Slap a firearm of any sorts into a machine rest and take away the human elements...

Stabilising a rocket starting from zero velocity at relatively high angles closer to vertical is different, but they do use spin stabilisation when required. Rockets designed for altitude also have the advantage of requiring less spin to stabilise as the media (air atmosphere) reduces in...

I'd appreciate that Chris F. I know there is a lot of knowledge tied up with a few individuals that carried out near scientific testing level over the decades with organisational resources. The problem is that most of it was only documented to a level required for a representative team to...

I'm not sure that the article in post #90 makes the assumption that the ideal barrel can be positively compensated and indexed to resonate in the vertical plane alone? The article avoids making a definitive statement by introducing a casual observation instead: Shooters who have attempted to...

When I started TR it was explained to me, it's easier to place a cup in the centre of plate than it is to put in the middle of a saucer. I don't know that the ratio of white:black aiming marks have really been explored, given a 300y aiming mark put up in error on a +800y frame is quickly brought...

Straight up, what a fantasitic effort by the authors and researchers, especially considering the equipment employed. First question is with regard to the calibration process. I didn't identify at which distance the calibration was done. If calibration was done at all three distances (10, 160...
