I took my Shiloh 45-70 out today. I tested a couple of smokeless loads 405 cast at 1450 about 1.9, 350 berry at 1425 for 1.4 but the best was 68 gr of Swiss 1.5 and a 535 postell that shot under 3/4 inch .74. I couldn't get my chrono to read will all the smoke! I will use the Berrys 350 for plinking and the 535 black powder load for hunting and serious shooting.
If anyone has tips on how to chrono BP loads, let me know.
