I have rifles pretty much figured out but approximately how much in muzzle fps loss will I get if I cut 6" off my 20ga 26" turkey barrel? Shooting 3" Federal #7 Heavy's.

Thanks
Jim

BE STRONG IN THE LORD, AND IN HIS MIGHTY POWER. ~ Ephesians 6:10

Socialism is a philosophy of failure,
the creed of ignorance,
and the gospel of envy,
its inherent virtue is the equal sharing of misery.
