I was under the same impression, but wwb (1020fps) has noticeably less recoil than 5.0gr of N320 (951 fps). It’s only 4 ports in a V angle (2 on each side) near the muzzle. It must be closer to a compensator than you would think.
I have a ported barrel in my Atlas custom 2011 and I’m looking for a handload to take advantage of the ports. The porting works really well using Winchester white box 180gr chronoing at average 1020fps. The wwb has less felt recoil than my n320 limited load. I’ve tried power pistol but that seems harsh, no matter what pistol I’ve tried it in. Do you think I need a slower powder than power pistol? Any other suggestions?
