For a gas gun, I would strongly recommend the .30 cal cans for 6.5mm bores due to back pressure.
For a bolt gun, the 6.5mm cans are like disconnecting an air tool from the hose with the Ultra 7.
For SBRs, you eliminate the insane muzzle blast and concussion felt around the area, with a much more tamed muzzle noise, nothing Hollywood like the Ultra 7 on a bolt gun.
