It is good that he covered it.
I think it is ironic they are both designed to do the same thing by the same parent company yet be different in terms of performance. If there was a superior bullet I would expect the company to go with that bullet, not offer two different ones. If you don't consider that ironic that's fine.
You thought wrong. What you are referring to is market cannibalism which is not the case. Some firearms will perform better with one bullet or the other. Notice that the author of the video used ONE pistol. The topic discussed is the effectiveness of the bullets.
Factories produce a wide variety of ammunition (i.e. Sierra TMKs, non tipped MatchKings, moly, non-moly, cannellured etc.) in seemingly similar offerings because they can perform differently in a variety of firearms.
What I didn't get information on in the OP video is jacket thickness.
What is a "superior" bullet? One that has a high BC or one that stops any person with one shot? Is accuracy a factor? There is no ONE solution.
Stop derailing threads especially in these technical posts. Take your bullshit to the Political section.
