Do polygonal rifled barrels yield more velocity than a traditional rifled barrel?
I don't have a normal rifled 9mm anymore of the same barrel length as my Walthers to compare.
My PDP may just have a fast barrel but the velocities I seem to get with it are usually higher than I normally think they should be.
I was just wondering if anyone else has tested this?
