Muzzleloader overpressure

[whoami-72]

So, as a centerline reloader I can tell when I'm getting close to being over pressure. However, on a muzzleloader, how can you tell? Does it change from musket caps vs primers?

If you're running black powder, it's pretty hard to get the pressures up that high, frankly. There's a very wide window to work with.

It's hard to get over pressure with BP. You'll get a big flash and huge smoke before you have issues. Most find better accuracy loaded for efficiency.

No.

Stick with the standard 150 grV max for bp and subs like 777, and 120 grV max for Bh209 and you’ll have nothing to worry about.
