      Good info but I have a question….

      “Powder Description/Positive ID/Type/Charge Weight: BE-86 8.0 / 8.0 / 8.0 grains (Changed originally posted this as Power Pistol)”

      How is the powder ID’ed? This one was originally posted as Power Pistol but was changed to BE-86, why was it changed?

        At the time that pull down was done BE-86 was very new to the market. Further study (actual known BE-86 powder samples) and some tested loads helped.
        Understand that Power Pistol (BE-84) was a derivative of Bullseye but the burn rate was changed and cut flakes were slightly larger.
        That being said BE-86 is also a derivative of Bullseye but the burn rate was changed (BE-86 is slower than Bullseye but slightly faster burning than Power Pistol), flash suppressants were added and cut flakes were slightly larger than Bullseye but smaller than Power Pistol.

      There are 3 loads for a 150 grain bullets. Would it be possible to use that data? Starting one grain, lower and working up for a lehigh 150 grain defender bullet

      I haven’t worked with Lehigh bullets, but seems like they are longer if I’m recalling correctly, so pressure could a issue

      Lehigh bullets is what underwood is using. lehigh load data is quite anemic compared to underwood load data. I was thinking of starting with the Lehigh data and working up to somewhere less than the Underwood data

      Underwood 140gr Lehigh Defense Xtreme Penetrator (100% solid copper) look at this billet above, and the lehigh information states that the length is .590 not .6295.
