Two and a half tenths sucks to holdIn the late eighties the little R&D corp. I was VP of was chasing military contracts. One was for bug sized drones, another was for real chocolate that didn't melt in desert temperatures. Both of these things came to be as well as insect cyborgs that carried cameras and microphones. They wanted the bugs for indoor use, to fly through doors unnoticed when opened to let someone in or out. I think they got most things on their wish lists although some took over a decade to get working. One of our projects was building a 1/3 cubic inch freon compressor. Introduced me to the world of micro tolerances where the machines couldn't cut it and final fit was by hand! Tolerance, 0.00025 of an inch maximum!

Agreed. I've spent many days at Camp Perry. I volunteered to pull targets for the final 20 in the President's 100. It was shot at 600 yards slow fire with AR 15s. I watched as the shooter at my target put all rounds in the 9, 10, X ring. Amazing what they can do with the right equipment and skill.After that I would go to the job shop machine shop next to my shop that mostly turned out short run productions to runs of a few thousand pieces and spend a day cutting. First time I asked him about tolerances I asked him if five tenths or so was good enough. He replied that was a bit rough. It took me a second or two to realize that I meant .0001" and he meant .10"
The tightest tolerances I ever held was with a handheld tool. The size had to be gaged. To get the necks that consistent I had to hold that danged tool in my hand for fourteen hours to turn the necks of 28 pieces of brass. Once it got warm it had to stay warm. Everything else was done one handed that day. However, that brass sprang back to proper size, never any neck sizing needed and lasted the life of a custom barrel even loaded more than a little warmish. It also let me shoot under the world record for five 5 shot groups at 100 yards in the hotly contested 10.5 pound benchrest class. I wasn't the only one to unofficially better the record but my good friend and master bullet maker Jef Fowler set the record when it counted and held it for over a decade!
Want to see over a hundred super anal OCD people in one place? Go to a major benchrest match. It was fun though, and I can't imagine a greater bunch of guys and gals!
If they really had OCD, they would be calling it CDO, as the acronym should be in alphabetical order.Want to see over a hundred super anal OCD people in one place? Go to a major benchrest match. It was fun though, and I can't imagine a greater bunch of guys and gals!
^^^^^ or talk to my gunsmith buddy who probably made a rifle or two that's being used there !
Another friend of mine is also that bad he sold a bunch of reloading brass for my rifle that wasn't the weight he wanted for one of his target rifles .
So I took it home reloaded it and it shot great for me ha ha !
