. Note that there are no photo's/video of the actual "print" operations, a nice video showing 10 percent, 30 percent, and 75 percent of the barrel fabrication, along with a Rockwell 'C' harness test, and ultrasonic scan of the gun barrel would go along way in providing credence to use of the...

............as some on other websites would have you believe, that it would take that kind of blind faith to believe a fully functional metal gun firing full samii loads could be produced using a 3D printer metal cintering printer, helical rifled barrel and chamber included. Guess we need to...

Looks like a 4 screw adjustable to me, and know that just because it is adjustable does not make it any more repeatable than your existing scroll chuck, if that is your sole criteria for switching. Also, beware that you are going to need more than just a standard flat backplate, you will need...

Lou, per your observation I ran a set of deltronic pin gauges across my own Juenke machine and got similar results for many of the pins that I inspected, those that did show variations I noticed they contained large excentric areas between the ground ends, in the unmachined caste centers, which...

. Hi Lou, my favorite and what I believe is the most accurate description of the Juenke machine was posted on this messageboard back in 2001 by a professional engineer and br competitor, describing the machine to consist of an; "oscillator circuit (a sine wave generator) that has its...

. I spun some Nosler solid E tips, 180 gr. bt's, they all spun to less than one deviation unit over the entire bullet circumference surfaces including all the way up to the tip ogive surface, better than any of all the custom br copper/lead bullets that I have spun over the last 20 years. I...

. Upside, a rail will shoot 10 shot 30 cal groups with no noticable recoil affects which can sometimes be troublesome with 30 cal stocked rifles and probably have fewer fouling issues with 10 shot strings due to a larger bore.

. And the Canadians know how to drive their bobsleds without leaving more paint on the track walls then their sled fenders, unlike the American drivers.

Makes me wonder if Remington is still hammer forging its latest barrels on to chamber/bore mandrels like they have in the distant past.

. 12 percent beneficial affect is less than typical placebo results for most medicinal substances.

http://benchrest.com/archive/index.php/t-49251.html Very good read, thanks for the link.

The adjustment mechanisms that you see in the Young rail are primarily for competition use to traverse between sighter and record targets in a very precise and repeatable manner, these mechanism would not be necessary for your AR testing but would not inhibit it.

. An interesting read about the very earliest railgun developement and testing, Mann testing fixtures; http://riflemansjournal.blogspot.com/2010/12/i-n-arms-factories-in-ballistics.html...

Just my observation as someone who has made, owned, and shot several different types of railguns for competitive BR............almost any barrel blocked railgun can be made to accept an AR by clamping to its barrel. About the only unusual alteration that would have to be made would be to have a...

Boyd, why the flat bolt nose for the 6.5 and not a cone?

What part are you not adapting too?

. Should not make any difference, the gas port block is located appx. 12 inches up the barrel from the bolt face, gas system is well pressurized and actuated before bullet exits barrel crown. Ive variable ported a .308 BAR in order to reduce case extraction throw and it takes quite a bit of...

. If you are looking for value and precision full length sizing, order a Wilson full length sizer.........not as fast to use as a high end threaded full length resizer but as or more precise and less dollars, may have to order directly from Wilson as many distributors do not carries these in...

Just use a .22 centerfire lead bullet core or a captured .22 rimfire lead bullet, both are almost pure lead and can be upset to fit in your slugged barrel.

. Take the barrel/action fixture out of the vise holder and replace it with a slave stock fixture.
