Benjamin Marauder .22 slugs

There’s a lot to unravel here. Have you found a good fill?

Have you tested pellets around the same weight as the slugs you want to shoot?

What is your end goal?

Every rifle is different; have you tried or are willing to try a bunch of different brands?

Do you have a chronograph?

Are you willing to accept honest feedback?

Not trying to be a jerk but finding the “best” is going to take some tinkering.
