    Molten Salt Annealing Rig

    I´ve read the "paper" carefully, I feel it´s like Churchill´s statistics... you make them what you want. From purely technical standpoint, I don´t believe hardness is necessarily representative of material ductility/flexibility. There are lot of materials that are hard and brittle, then those hard and flexible and anything in between. The strength with which the case neck holds the bullet is a function of the material springiness (bullet expands the neck and the neck spring-back is what really does the work). As far as reloading application, I´d see more value in a test that would pit non-annealed cases against cases annealed by different methods, and measure bullet seating force (not for absolute numbers, but for case-to-case standard deviation) and chrono the resulting reloads. That, side to side, would have practical value. As for my own experience, I noticed improvement in both velocity SD and case longevity when I started annealing by gas flame a few years back. Thus, I decided annealing has value, because I saw the difference comparing to repetitive reloading of non-annealed brass. Last season, I turned to salt bath simply because it´s superflexible as to the case type - you don´t need special case carriers for different sizes etc. I can now say that my results haven´t changed a bit, which to me translates to salt bath working to the same practical result as the flame I used before.

    King of 2 Miles in France

    Not that I know of. American guests were running a 416Barrett (Paul Phillips) and 375CT (Tacom team). Don´t think it´d spread amongst any euro shooters yet.

    King of 2 Miles in France

    Let´s see, I don´t have any better pics of the detailed results, so I hope they will be visible: Qualification: Finals & AGG: It was clear from day one that we were right on one thing in preparation: that if the competition is named after the furthest target doesn´t mean anybody will reach it over the elimination rules (you are out if you do not connect with the alloted number of rounds - cannot continue to distance B if you score zero at distance A). We concentrated on getting SOME points with more certainty (can get pleanty more training time and data behind a 338LM than a Cheytac variant, so I took what I can use), and see how that fares overall. Rather OK, as it turns out. Canjuers range picked for Ko2M has the specific treat of shooting over a great elevation difference (shooting line is 100m+ higher than the targets - I measured 11,5hPa difference just driving up). We were essentially shooting from a shelf. This isn´t about incline which you account for (and at the distance, you´re aiming up anyways 😄 ) but about the wind. 100m into flight the bullet is also all of a sudden 100m up above ground and into... what wind now? Your guess is as good as mine. Most calibres involved were of a Cheytac variant, where the popular theory would say that a 1450m target should be easy. It wasn´t, and as you can see about a third of the teams didn´t connect and were eliminated from the first target right away. We were 10th after the qualification and kept that position after the finals. Only two out of ten finalists had ANY hits on finals day! First finals target was set at 2430m. Bruno, the winner was 8th after the qualification and his points advantage wasn´t that great over us. The 375Snipetac he was using is pretty much a 375CT improved. This shows we were roughly at the same playing field between the calibers at the qualifying distances. The finals distance proved too much for our 338, though the camera team reported we were impacting as close as between the target stand leg and target itself on two shots. A close miss is still a miss, in the end Bruno did great and was the only shooter to hit all distances in the finals, including the 3270m on his second shot. The man was on fire! @Bradders: we built this 338 with that old bull barrel blank you sent me about a year ago... Our equipment list: Modified/remachined CZ550M action (yes, a giant Mauser) fitted into AICS chassis; .338/1:10´" barrel finished at 29"; Ritter&Stark Muzzle brake; IOR 6-24x56 scope; Bipod Czech TST Carbon; Ammo used: Lapua case, Fed215Magnum primers, RS80, Berger 300Hybrid -> 865m/s Spotters: Leupold Mark 4 and Swarovski STR80, both with reticles. The Swaro is simply phenomenal. Last pic: in the background, Bruno is in the middle of his winning run. Waiting on the table closest to the tent is my rifle (10th overall), in the middle a 375CT that finished 11th behind us and nearest to the camera is Alexandre´s PGM Hecate 50BMG. Alexandre and his team finished 9th.
  4. We´re back and already looking to the next round. Canjuers, France, 20-22 April 2019 Now that the pressure of the competition is over, only good feelings settle in and memories remain. Eduardo, Philippe, Patrick and their teams showed immense effort to bring this first-in-Europe meeting to life. I am happy for everybody that those efforts and results obtained were immediately recognized by the French military on site as beneficial to the ongoing technical development and future formation of the troops. It was an honor to be part of this industry leading event, competing yet working together on the mutual goal of pushing the limits of known technology and what lies beyond. We may have not leaped forward, but steady steps were taken - no ground given. Thanks to the entirety of my team for their continuous support and patience over the past year of preparations and strategy adjustments. Following the lead requires immeasurable faith and I´m humbled by your work. For us, reaching the finale is a notable result shooting the smaller, 300 grain 338 caliber bullet compared to all other finalists pushing 375 caliber or even bigger numbers. Our success was possible thanks to Kahles aiming and Swarowski spotting solutions, permitting minute corrections based off visible terrain impacts in the target proximity over the distance of over one mile. We are happy to have proven that with superior quality of optical systems, brute force of bigger calibers is not always a necessary prerequisite for bridging the distance. What is your choice to depend on in the field now? I look forward to seeing you all next year, pushing further forward.

    HbN users: what's your cleaning regime?

    My longest-in-use HBN treted bbl is my 6Br. I do the same cleaning routine after every range trip (anything between 30 - 70 rounds): push through one dry patch to get away loose debris, then three soaked patches (Shooter´s choice or Robla) and let it rest for a few minutes. Patch dry. In the beginning I tried to repeat a soaked patch after the routine but got no more copper indication, therefore I believe any further cleaning would be wane. I´m on this routine for almost 2k rounds now.

    AI Ax rifle accessories

    Not sure about the "hardware" accessories, but as for minicheekpads, there is a French outfit that makes them fitted to particular rifle models. I dare say their quality is better than the american stuff and it takes about a week or two from order to delivery. Link: http://www.blac-tactical.com/catalogue_blac.pdf

    RPA quadlite into rem 700 stock?

    Depends on the chassis model you´re looking at. The ones with tubular forends could be tricky or right impossible. I have my 2 RPAs in AICS, which is perfectly fine. When I was checking the dimensions on the 1st gen AX chassis it did not seem possible.

    Lovex D060 was actually developped for the purpose of reduced loads in order to avoid risk of secondary combustion/expolosion with very low density loads as used in cowboy shooting or when reloading old large volume (originally black powder design) cases with small amounts of smokeless powder. Look for AA5744 reduced loads on American forums, essentially the same powder in another brand keg.

    GAU-5A/A Commando Carbine

    Just off the title first thing that came to mind was the A10 warthog 😄 Very nice as a modern nod to the classical firearm, thanks for sharing
  10. I have a mint Discovery HD 4-24x50, FFP illuminated reticle, MIL/MIL, 34mm tube with low Recknagel rings that I would like to trade for a SFP scope. I need to have 4x power, MIL adjustment and adjustable parallax; the rest of the zoom range and other specs is not that important.

    338 300gr Scenar - pointed?

    I actually have Davy´s die for pointing and can recommend it wholeheartedly. My question really isn´t on the "how to?" level, but more of "worth the effort based on actual experience?", because I haven´t shot the 300 Scenar (pointed nor factory virgin) myself before. BTW for what you note, 6.5mm 139 Scenars (pre-L) DO benefit from pointing, shrinking the 1000m vertical by noticeable 15% when fired at moderate volocities from a Swede. Therefore I reasoned, at least in theory, that the new L-class designs with wider meplat would benefit too.

    338 300gr Scenar - pointed?

    With the current shortage of 300gr Hybrids I'm seriously pondering the possibility of improving upon the 300gr Scenars and developing a new load with them. Anybody bothered pointing these before? What results have you achieved?
  13. I had a 50 mm objective lens on it ...no problems

  14. The height of the 35mm mount, please? Considering for the 42mm objective 3-18. Thanks.
  15. Sounds almost like LongShot history class rules, am I right? Took 3rd place with a 1896/11 Schmidt-Rubin a year ago. The 300m target is tricky for the older guns in that windy environment. Swiss guns are hard to beat for the task. For Military/Open sights category, a bog standard k31 will do, or you can grab a G11 type rifle for longer sight radius. In open, a diopter and closed front gives advantage. K31 with a target diopter is admissible, I believe, but be warned that WaffenFabrik Bern original sights are more expensive than the rifle itself. Otherwise in past years we´ve seen good targets shot with 1903 Springfields, Garands, P17s and a BAR, actually.
