I put a few 30-30 rounds through the chronograph.
Remington store bought ammo 150gr, 2380 & 2419 fps
IMR 3031, 150gr, 2250 fps
RL 15, 150gr, 2141...thought that was a little slow so sent another...2131 fps...guess that's just what it is.
First time using my chronograph. It was great fun to see the numbers. I ordered the Lee crimp die this morning as well. Always fun putting a load together.
