220's are a mouthful! The G20 hung up with one which happens with those in some pistols.
Great video as always from hickok45! 8) The Wide Nose limits the angle of approach, can add some drag as it tries to feed. I know that some seated these down to 1.4242" (DT) to allow them to tip over as they feed up the pipe. However the charge weights may need to be adjusted as you seat that longer bullet deeper to keep pressures under control.
I let him know Underwood makes one a little cheaper with a bit more pop. Maybe he will feature those in his next video.
I would love if he tried some heavy grain ammo in 6" hunting barrel. The hardcast 230gr was awful in a stock length Glock barrel.
Great video, good to know the BB 220 works in the stock barrel too. I used the DT 230 in my G29SF and a stock length Lone Wolf barrel for a test; shot through a dead hogs head at 3ft (like a finishing shot,etc) and got complete penetration and into the dirt! I didn't shoot for groups though. I also like the BB 155 XTP, it was found under the skin on the far side of the head, but the skull was just shattered inside!
