Was using the Lyman 340 gr. That info got lost when I reworded a sentence. The 1620 fps load was a factory Kynoch that a friend gave me. He had bought over a 100 cartridges at a gun show as .43 Mauser, but most were 11 Belgian Mannlicher and many of the rest would not fire. When fired over the Oehler 35P I knew it was a thumper by the recoil but was still surprised at the velocity. Will give 4895 a try. Note: My 5744 load owns a CBA Military Big Bore record and some day they'll update the website to show it. Thank you.
