I think the military rule for flintlock muzzle loaders was you had to load and fire 15 rounds in three and three quarters minute.
I seen OLD Winchester74 and Remington nylon 22 rifles that can shoot as fast as you can pull the trigger.
And I still get a thrill out of a Remington Model 8 made in 1906. Enough to make an anti-gun radical lose bladder control!

lol. I need more range time, more practice with the old .54
A rifle I couldn’t own in California because it’s .50 caliber.
