Weird Velocity: RL-16 in 30-06

[rustyshackleford]

I've been toying with Ramshot Hunter, H-4350, and RL-16 in the 06 and I just received a brand new magnetospeed. So I shot some 180 NBT over RL-16 to measure it and I got increasing velocity with increasing powder charges up 55.4 gr, the max per Alliant, and at 55.7 the velocity dropped from 2743 ft/sec at 55.4 to ~2700-2720 (3 shots) at 55.7. Have you guys ever seen anything like that? I thought maybe it was the chrono but I shot another load I had already verified over another magneto and it checked out.

Yes, that is an accuracy node or plateau and it is what you are looking for.

I've done work ups and I've never seen one drop that much. Usually for me it's been a 0.6-0.9 gr span and the velocity varies by maybe 15 ft/sec. 40 ft/sec variance doesn't seem like much of a node.

That is a big drop but you get the idea
