hi, i'm new to the forum. i am interested in info on ported, extra long barrels for Marlin 25N. i intend to use it for coon hunting, frog gigging, and pesky critter removal so it has to be as quiet as posible w/o a silencer. i shoot CCI CB Long rounds for their noise levels. they are fairly quiet compared to the Long Rife rounds but i want silent and legal if posible. any info would be much apriciated, thanks!!
