  1. I think the fact that you used WH40K as an analogy says everything we need to know about you.
  2. Fallacious. SpaceX has received something on the order of $10 billion in contracts from NASA ON ALMOST ALL OF WHICH IT HAS DELIVERED. Compare to, say, Boeing, which has received billions for one contract alone and still has not delivered. People want to claim SpaceX's contracts with the US government are a subsidy. But the magnitude of these contracts put together may be less than one legacy contract which is never resulted in anything or still has not delivered, and yet SpaceX has delivered so much more. There's no comparison. Dinosaurs like Arianespace want to try to pass "SpaceX takes government money too!" off as of they're not about to go extinct.
  3. Ian Holm (Peter Jackson's Bilbo) has died. For once, I'm quite sad about a celebrity death.
  4. L to R: .224 Zoomer Magnum, .22 Rapier, .237 Antidote, .257 Flap, .283 Fudd.
  5. CONFIDENTIAL AN EVALUATION OF CANDIDATE RIFLE CALIBERS FOR THE SIOUX SCOUTS STANDARD SEMIAUTOMATIC RIFLE (SSR) THUNDER BASIN PROVING GROUNDS September 25th, 2222 -cartridges for five candidate calibers and several chambered barrels each were received for testing during the week of July 7th, 2222. These were from teams lead by Curler, Neelam, Flapper, and Tockson, and two projectiles with a shared case from a team led by Griffin. The measured characteristics of their respective rounds were as follows: .224 cal (Curler): Case Length: 1.875 Base Diameter: 0.408 Case Taper: 0.5 deg Shoulder angle: 25 deg Neck length: 0.233 Rim thickness: 0.049 Rim height: 0.123 Groove angle: 36 Bullet diameter: 0.224 Bullet length: 1.1298 Cartridge overall length: 2.576 Proposed case capacity: 38.56 grs H2O Measured case capacity: 38.67 grs H2O Proposed bullet weight: 76.07 Measured bullet weight: 76.07 Proposed i7FF: 0.853 Measured i7FF: 0.796 Proposed G7 BC: 0.254 Measured G7 BC: 0.278 .224 cal (Neelam): Case Length: 2.00 Base Diameter: 0.400 Case Taper: 0.80 deg Shoulder angle: 25 deg Neck length: 0.220 Rim thickness: 0.060 Rim height: 0.139 Groove angle: 45 Bullet diameter: 0.224 Bullet length: 1.260 Cartridge overall length: 2.71 Proposed case capacity: N/A Measured case capacity: 37.61 Proposed bullet weight: 83.3 Measured bullet weight: 84.0 Proposed i7FF: 0.801 Measured i7FF: 0.682 Proposed G7 BC: 0.296 Measured G7 BC: 0.351 .243 cal (Griffin): Case Length: 1.85 Base Diameter: 0.4 Case Taper: 0.5 deg Shoulder angle: 25 deg Neck length: 0.237 Rim thickness: 0.060 Rim height: 0.1274 Groove angle: 45 deg Bullet diameter: 0.243 Bullet length: 1.422 Cartridge overall length: 2.8 Proposed case capacity: 35.75 grs H2O Measured case capacity: 35.86 grs H2O Proposed bullet weight: 85.75 Measured bullet weight: 84.65 Proposed bullet weight: 103.2 Measured bullet weight: 106.0 Proposed i7FF: 0.78 Measured i7FF: 0.618 Proposed G7 BC: 0.266 Measured G7 BC: 0.331 .257 cal (Flapper): Case Length: 1.975 Base Diameter: 0.473 Case Taper: 0.50 deg Shoulder angle: 25 deg Neck length: 0.244 Rim thickness: 0.0539 Rim height: 0.152 Groove angle: 36.44 deg Bullet diameter: 0.257 Bullet length: 1.374 Cartridge overall length: 2.8 Proposed case capacity: 52.22 grs H2O Measured case capacity: 52.20 grs H2O Proposed bullet weight: 128 Measured bullet weight: 129 Proposed i7FF: 0.849 Measured i7FF: 0.773 Proposed G7 BC: 0.326 Measured G7 BC: 0.361 .283 cal (Tockson): Case Length: 1.8898 Base Diameter: 0.473 Case Taper: 0.34 deg Shoulder angle: 25 deg Neck length: 0.241 Rim thickness: 0.054 Rim height: 0.1615 Groove angle: 33 deg Bullet diameter: 0.283 Bullet length: 1.5 Cartridge overall length: 2.8 Proposed case capacity: 49.34 grs H2O Measured case capacity: 50.81 grs H2O Proposed bullet weight: 122 Measured bullet weight: 124 Proposed i7FF: 0.824 Measured i7FF: 0.717 Proposed G7 BC: 0.264 Measured G7 BC: 0.308 CONCLUSIONS: All candidate rounds met the requirements while eking out substantial margins in cost, weight, and recoil versus legacy calibers of comparable capability (e.g., .308 Winchester). No candidates tested showed any concerning deficiencies in critical metrics like penetration, or retained energy. Every single candidate round tested at a lower i7 FF than proposed. No candidate round tested at a higher i7 FF than 0.8. All candidate rounds produced test velocities close to their proposed velocity. Some candidate rounds had marked (>1gr) deviations from their proposed projectile weight, but this was deemed a byproduct of manufacturing and not considered critical. No candidate round had less than 800 yards range with at least 700 ft-lbs striking energy, which is considered exceptional performance, even considering the small caliber of some of the rounds. Pine penetration for all rounds substantially exceeded the minimum specification, indicating suitability for hunting large game at medium to long distances. Trajectory and wind drift for all candidate rounds was excellent. In each metric, the rounds were ranked, shown by the tables below. Velocity: 1. Neelam 2. Griffin (106) 3. Flapper 4. Griffin (85) 5. Curler 6. Tockson Energy: 1. Flapper 2. Griffin (106) 3. Tockson 4. Neelam 5. Griffin (85) 6. Curler Trajectory: 1. Curler 2. Neelam 3. Griffin (85) 4. Flapper 5. Griffin (106) 6. Tockson Wind Drift: 1. Griffin (106) 2. Neelam 3. Flapper 4. Griffin (85) 5. Curler 6. Tockson Pine Penetration: 1. Flapper 2. Griffin (106) 3. Neelam 4. Curler 5. Griffin (85) 6. Tockson Materials Cost: 1. Neelam 2. Griffin (85) 3. Griffin (106) 4. Curler 5. Tockson 6. Flapper Weight: 1. Curler 2. Neelam 3. Griffin (85) 4. Griffin (106) 5. Flapper 6. Tockson Recoil: 1. Curler 2. Griffin (85) 3. Neelam 4. Griffin (106) 5. Tockson 6. Flapper All competitors were very close in all metrics except cost, weight, and recoil. From these, it is immediately evident that the 106gr projectile proposed by Griffin's team was the most cost-effective round of all tested, scoring first or second in all performance metrics besides trajectory, where all rounds were extremely close anyway. In addition, this proposal's projectile possessed several key attributes which were decisive in its selection: A very high sectional density (second-highest among projectiles tested), unprecedentedly low drag, and an economical expanding projectile which remains front-stable during penetration. Most other proposals used steel full metal jackets, or were made entirely of pressed steel, which are designs that, while they provide excellent penetration characteristics, do not remain stable throughout their path and often deviate from the shot line, and which also do not provide any expansion to widen the wound cavity. These characteristics are considered acceptable, but those of an expanding, front-stable bullet are certainly preferred. Griffin's other proposal was an 85gr bullet of novel construction that, while very interesting, was considered far riskier, while possessing less desirable ballistic characteristics anyway. It could, however, form the basis for a promising armor piercing projectile, and so funding for further study of this design is recommended.
  6. Congratulations @Gripen287. Justification and commentary to follow.
  7. DAKOTA UNION CARTRIDGES AND ORDNANCE DEPARTMENT BULLETIN BULLETIN BULLETIN FOR IMMEDIATE RELEASE: THE DAKOTA UNION CARTRIDGES AND ORDNANCE DEPARTMENT HAS TESTED CANDIDATE ROUNDS DEVELOPED BY THE FINEST SCIENTISTS AND ENGINEERS THE UNION HAS TO OFFER. THESE ROUNDS WERE PUT THROUGH THEIR PACES ON THE MASSIVE ORDNANCE 5,000 YARD BALLISTIC TESTING FACILITY GROUNDS IN THUNDER BASIN, COMMONLY KNOWN AS THE THUNDER BASIN PROVING GROUNDS. THE COMMISSIONER OF TESTING IS PLEASED TO REPORT THAT ALL CANDIDATES PERFORMED EXTREMELY WELL, AND HAVE EACH IN TURN THOROUGHLY JUSTIFIED THE UNION'S SELECTION OF A BRAND NEW CARTRIDGE & CHAMBERING FOR THE SIOUX SCOUTS UPCOMING STANDARD SEMIAUTOMATIC RIFLE (SSR). HOWEVER, WHEN ALL IS SAID AND DONE, ONE MUST BE CHOSEN, AND THAT CHOICE WAS CLEAR: THE .236 CAL-1.85 ROUND DEVELOPED BY ALDO GRIFFIN AND HIS TEAM SHOWED SUPERIOR PERFORMANCE IN EVERY RESPECT, WHILE MODERATING BOTH WEIGHT TO THE SCOUT AND COST TO THE LIENHOLDER. CONGRATULATIONS TO GRIFFIN AND HIS TEAM FOR A JOB WELL DONE.

  9. Ahahahah I didn't think any of the other entrants would take my fluff to heart, I was just spinning a yarn, not setting new requirements!
  10. It's basically a factory 6mm AR. Great round.
  11. NOT CANON From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota my boy! The news has come down the pike, Senator Brown's aide sent me a package this morning with the requirements for a new round for the Sioux Scouts and that fancy new semiauto they're designing. This will become our top priority project. In this envelope you'll find a copy of the solicitation, which is expected to be passed in the Senate in the next appropriations bill. Get to work! From: Otaktay Lewis, Engineer To: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant Mr. Lewis, sir, I've completed a study on a new round which will minimize weight and cost while meeting all of the requirements. Please find enclosed a dossier for the .20 Sioux, which thanks to its very efficient steel projectile and case will achieve the desired performance while costing less than 4¢ per round. I think this could be a huge enabler for the Sioux Scouts! From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota! I found a typo in your dossier. It should be ".260" Sioux, not ".20". From: Otaktay Lewis, Engineer To: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant Mr. Lewis, sir, With the utmost respect, sir, it's properly called ".20 Sioux". The round is .204" caliber. From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota! I know you worked hard on this, and I'm proud of you, but that just won't do. No one wants to draw hash on a buffalo with a 20-bore! Make it bigger. And the bullet is too light, 70 grains is nothing! From: Otaktay Lewis, Engineer To: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant Mr. Lewis, sir, I'm not sure I understand. The .20 Sioux will meet all of the Sioux Scouts' requirements with ease, while being extremely affordable. From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota, my boy! Make it .260 caliber or greater, great work! From: Otaktay Lewis, Engineer To: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant Mr. Lewis, sir, I've completed work on the revised round for the Sioux Scouts. Please find enclosed a dossier on the .260 Sioux, which is expected to cost just over 4¢ per round. It was tough to pinch pennies while meeting the requirements with such a wide bullet, but this manages it! From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota my boy! Fantastic work as always! I'm concerned though that the round you've designed produces less than 2,000 ft-lbs of energy. We should definitely bring that up a bit! And a 90-grain bullet? That's a little low, let's try at least 108 grains! From: Otaktay Lewis, Engineer To: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant Mr. Lewis, sir, I don't understand. Increasing the muzzle energy and bullet weight will require dramatically increasing the propellant charge and material consumption, which will increase cost unnecessarily! Plus, bullet's drag is low enough that it doesn't need to be heavier than 90 grains, or have more than 1,500 ft-lbs to meet the requirements you sent me. From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota! That's quite enough of that backchatter, let's go with 2,000 ft-lbs and call it a day, shall we! From: Otaktay Lewis, Engineer To: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant Mr. Lewis, sir, After considerable effort, I've finished the revisions you requested to the new round for the Sioux Scouts. Please find enclosed a dossier on the .260 Sioux Mark 5. Note that it produces approximately 2,000 ft-lbs with a 108gr bullet fired at an instrumental average of 2,875 ft/s. Now, this does mean it costs almost 6¢ per shot, but on the plus side it exceeds the energy requirement by about 300 yards, and the pine board requirement by over 400 yards. From: Arthur Q. Lewis, Director of Production at Rapid City Union Ammunition Plant To: Otaktay Lewis, Engineer Ota! It's perfect, excellent work! I'll send it off right away! Congratulations, I'm proud of you, son!
