Looks like really sloppy fit of the firing pin to the hole.
Either an M&P Shield 40cal or M&P compact 40cal. He owns both so not sure which one he tested in.Fired in a High-Point perhaps?

Your looking at Berry's plated data. He is using FMJ which max is 5.5.I just checked Hodgdon's load data. He is at max with 5.0 grains of 700-x.

You know what I didn’t think of him using scoops. He wanted to use the one that came with the lee dies and I told him no. He says these are all hand weighed in a digital scale. When I get a free moment I’ll see what’s wrong.I still think he ought to cut his loads and then see how the primers turn out. It could be an over sized primer hole, and it could be more powder in the case than that particular pistol can handle.
And it could be the reloader is using scoops and not verifying the weight with a scale.
Why?IDK I dont see a problem.
But I wouldn't shoot his reloads
I looked at the primers in person and one has a very sharp cut on it that appears to be from the firing pin.
Kahr> "Primer wipe" is a teardrop-shaped firing pin impression, accompanied by a drag mark (scratch or gouge) following the "point" of the teardrop and leading away from the primer, sometimes into the brass. This is because the firing pin does not fully retract after the round has fired and the slide is traveling back during ejection, causing the case to drag across the firing pin as it is thrown clear. It is not in any way harmful, except sometimes to the case if the primer pocket edge is gouged. Kahr will tell you it is a normal condition for their pistols, even saying so in the owner's manual.
