Yup, 20".
Best length for velocity and accuracy out of the platform in my opinion. Short barrels have their purpose, and do their jobs well, but the cartridge was designed with a long barrel in mind to gain maximum velocity so the bullet will have enough speed to tumble and break apart.
WINNER WINNER, Chicken dinner !
Wer did u git yoursef al edimucated abut cartridge design an such. It anit nuthin but voodoo an hokuspokus.
Anybody on the ol' inernets no's it all coms down to how short yer barrel iz an how much u paid.
