If you're using the Remington .45-185 JSWC start with 4.6 of Bullseye or 4.8 of WST.I would like to duplicate the 185 SWC Federal Gold Medal Match load for 45 acp. Muzzle velocity is around 770 fps.
I am planning on using the load for 50 yard bullseye matches.
I had to talk to a primer chemist at Federal a couple of years ago on a business matter. At the end of the conversation, I asked about the "Factory Load" for their .45 Auto Match product. He chuckled, and explained that there isn't one- he went on to explain that they use bulk powders, not canister powders. They have the equipment to measure pressure vs time, and they load to get the desired P-T curve. The load is whatever it takes to get that result with the powder they have on hand, which they purchase in really large quantities.You know what, I would be willing to bet dollars to donuts Gold Medal uses Bullseye. I dont have anything to support that conjecture.
I asked that, too. The answer was that the curve is most important; the MV turns out to be ~770fps with the desired curve, but, depending on the powder, it can vary and that variance may be significant. Recall, too, that they are using a SAAMI-standard test barrel and fixture under controlled conditions that you and I can't duplicate.GOVTMODEL: I understand going for a curve, does that also mean that FPS means nothing, or is there an average that they still go for?
