Sees Target

Sees Target (5/11)

  1. I believe this is mostly marketing with a pinch of engineering added in. Large distributors (Lew Horton) need unique/exclusive part numbers. Marketing needs a new product to sell. Different cylinder release or front sight. That's about all I can figure out.
  2. No signs of high pressure on the primer. Pressure high enough to rip open the case if nothing is supporting that case.
  3. The primer looks OK. No signs of high pressure. When I've overloaded a 9MM the primers always give an indication that pressure is High. Supported barrell or not. I'm leaning to our of battery
  4. I've load 9MM on the hot side. I stop increasing powder when the primers come flying out the back of the case. Next step is breaking a firing pin. Primers had flowed to fill the primer pockets way be fore auto depriming. Seek professional help. Don't hurt your self.
  5. Not exactly what you're talking about, but consider the following. We manufacturer coated bullets. We use Hi Performance bullet coating. Out bullets are brinell 12. When comparing lubed bullets to coated bullets, we consistently see velocities in the coated bullets higher than the lubed. Also, for about 10 to 20 rounds, the coated bullets keep increasing in velocity. Our only explanation is that the coated bullets are cleaning the barrels. So be sure you take enough samples to make sure your setup has stabilized.
  6. I was in the electronics industry back then, and a major gun manufacturer asked for a trigger design and a potting compound design. We won neither. Problem was NO ONE would sell them electronic parts to put in a gun!!! Too dangerous.
  7. Don't you remember in the 1970s or 80s there were primers that were fired electronically. Can't remember who made them, but it was a major brand. Never caught on and died away.
  8. That's even a different group. SASS is black power and federal primers!! And Bordertown has the targets at 10 feet or closer.
  9. I was at a SASS Match (Bordertown) I dealer had LOTS of Federal Primers Large/Small/Match/Magnum with prices of $110 to 130 per 1000. He sold a lot but did not sell out with 300-400 shooters in attendance. No Hazmat or shipping fees. So there is resistance at some pricing lever.
  10. Why do they need to know my birthday to sell me stuff???????
  11. Please do not put your hand over the slide. If the round goes off out of battery, your hand is full of brass. Seen it happen several times. All these methods work. But Better to be safe.
  12. I do know Linux (c or JAVA), I do not know Python. It seems to me the image recognition is the heart of the design. Get that correct and case handling will be easy. I also expect the positioning of the case is very important for image recognition.
  13. SAAMI spec on the extractor groove diameter is 0.347 +0.00 / - 0.020 And that is too much for a regular old moon clip to work with 0.347 grooves and 0.327 grooves.
  14. I would call Starline directly. They've always taken my calls and answered technical (dimensional) questions. Another assumption is that they make brass to SAAMI spec. I bet the extractor groove has a large (relatively) tolerence. 9MMfor example is +0.00 / -0.020
  15. The secrete ingredient is Lanolin. We but that online and mix with alcohol in a spray bottle Costs almost nothing and works great.
