    Quality invevestments made by the Russians, and some help for an interesting American

    ... Would this "outside world" inform your imaginary German/Swiss source?

    Quality invevestments made by the Russians, and some help for an interesting American

    Emouse, When you make silly statements under the guise of urbane contempt, don't get upset if someone calls you out.

    Quality invevestments made by the Russians, and some help for an interesting American

    Emouse, I thought you had some solid information on the German, and Swiss companies. Do you? Are you able to produce those tolerances on a "refurbished Pratt & Whitney"?

    Quality invevestments made by the Russians, and some help for an interesting American

    Do you have documentation supporting that Emouse? I would be genuinely interested in seeing it. Other than Border (sourced USA technology, and NDA protected), what other European company has the know-how to build the machine, and tooling, for precision cut-rifled barrels?

    Quality invevestments made by the Russians, and some help for an interesting American

    "Its interesting that he couldn't find an American company that 'fit' his needs."... I just had an extended conversation with an associate who claims an American company, that advertises the use of CNC rifling machines, took $500,000 to deliver a working example to Russia which incorporates...

    Did some testing of a solid today... @ 1k.

    One Shot, Yes, the lubricant is available in 10cc syringes at $25 each. Bohem was going to test for results with a hot jacketed round. Thus far I have not heard back, so I cannot provide any data for application to conventional projectiles, and throat erosion. I do have personal knowledge that...

    Did some testing of a solid today... @ 1k.

    Jfields, Frank is waiting for a new barrel to shoot the current 338 ZA projectile. We have been struggling with Emerson to get their software communicating properly with their CNC controllers for over four months now. The drill, and oversize 338 reamer are waiting patiently on the shelf. That...

    Cutting Edge 338, 375 & 50 BMG Projectiles

    Copper reached a low last month that we have not seen in the spot market since 2010. Chinese consumption has driven the price artificially high due to monetization of the metal. Now that their economy is once again stalling, copper will fall much further. It reached a high of almost $5/lb. from...

    408 Cheytac Components?

    Gunenthusiast, The first to be released will be the 338-408, but it is a small matter to make adjustments for the standard Cheytac 375 & 408 depending upon demand. 375-50 will follow, and again 50 BMG manufacture is only an adjustment if there is pressure to produce. The next priority would be...

    408 Cheytac Components?

    VaRandy, "... what did I miss about solving the crap brass problem?"... I should have been more clear. The "crap brass problem" will be solved by eliminating brass altogether. New propellants currently available, specifically; Alliant Reloader 17, 33, and 50, have opened a new door to flatter...

    408 Cheytac Components?

    "I wish it was easier to find some good 408 brass! I'm about done with my Bertram!"... There is a very attractive option to drawn brass cases that will soon be available... Follow Frank's "Did some testing of a solid... @ 1k" thread.

    Cutting Edge Bullets at 1500 Yards!

    ... I omitted a measure that may be significant to some shooters. Check the CE for transonic stability. Unless a composit construction is used, the CE is probably not going to perform well on this metric.

    Cutting Edge Bullets at 1500 Yards!

    Excaliber's question is a good one. Could I suggest a reply that cites at least one of the following advantages? : 1- Higher ballistic coefficient through improved form factor. 2- Higher inherent accuracy attributable to manufacture tolerances. 3- Higher potential muzzle velocities consequent...

    Lehigh 245 banded Solid .338 Lapua

    Extremegunner, I would like to see if the bore remains free of brass deposits when the four grooves are filled with lubricant, and what difference in ES, if any, occurs.

    Hexagonal Boron Nitride is a "ceramic", but ZA bore-lube is *not* HBN. I will be detailing neither the formulation, nor the prepration process.

    Did some testing of a solid today... @ 1k.

    Raufoss The compound that Frank is applying between the two rear engraving bands was tested on the 25mm Bushmaster, and found to increase throat life from 40 rounds cyclic mode, to 2,000 rounds @ 200 rounds per minute. I do not know ZA barrel life expectancy when used as Frank's video...

    World Record Shoot

    BTW, The admiral commanding the Scharnhorst was relieved of his command for this record shot. Apparently he had disobeyed orders by "wasting ammunition", in sinking "an old aircraft carrier", rather than merchant shipping... Leave it to the Teutonic mindset to miss the Forrest for the trees.

    World Record Shoot

    "The Wikipedia article claims the rotation of the earth had to be accounted for while aiming, (un)fortunately the Kaiser had plenty of Spin-D on tap."... Not only Coriolis, but they had to account for the vacuum of space over a portion of the Paris gun's trajectory. The Germans had developed...

    World Record Shoot

    Mailrat, "I believe the Long range record should most likely go to Germany's WWI "Paris Gun' "... On reflection, I suppose the entire city of Paris should be considered a "target"... but were both Coucy, and Paris moving at ~30 mph when the shot was taken? :) Even if this "record" shot only...

    World Record Shoot

    "Gneisenau and Scharnhorst were at 69°00'N, 03°10'E steaming at 19 knots on course 330° when smoke was sighted on the eastern horizon at 1546. Steam was raised for full speed, and course altered to close the enemy. By 1636 Gneisenau was making 30.5 knots and Scharnhorst, experiencing boiler...
