im testing my new barrel i installed, its a factory hdb68 barrel and we got around a 20 joule increase over the factory hdr68 barrel and using 1100 psi hpa, with Zrams 8.5 gram and 8 gram Juls v2s, my alloy hdr68 barrel is 12 inch and made for canada riotballs and hd-24 aluminum balls and i get 75 joules with that barrel and ammo as well, a longer barrel or more psi can get these up higher but for less lethal 55 joules is perfect
