[QUOTE="Wyo7200, post: 1052584, member: 82337"] Are you using magnum primers? Wondering if the fracturing of some granules (from the compressing of the load) coupled with a hotter brisance changes the initial heat of explosion enough to give Varget a faster burn and netting higher velocities. Have you noticed any unburnt granules leaving the barrel firing this round like, pitting on the magnetospeed bayonet? I got the velocity to bump up against your 2900 fps by increasing the heat of explosion, burn rate factor, and progressive burn rate while remaining under 60k. For safety, I don't want to post the numbers I entered, but each change was 3-4%. Big however is that there is no controlled scientific test that has been done to accurately scale the primers, besides the one done by a guy with a homemade device in his garage- [URL="http://www.castingstuff.com/primer_testing_reference.htm"]primer brisance test[/URL] and I am no chemist so just guessing here. You and my brother have some serious voodoo going on... Are you left handed by chance? [/QUOTE]
