GPM I think that may be unother urban myth and there is probably other causes present ie primers not fully seated.
However, having said that, I have read in the Oz target shooting of shooters claiming poor ignition using Palma brass and std primers. Hence some use magnum primers. This story emerges on a semi regular basis so I have to admit there may be something to it.

I have been using Palma brass now since 2019 (admittedly not in freezing cold weather) and have had no problems. My ESs are lowered over std brass however my ave velocity is down a tad, nothing significant.

I also have Peterson SRP brass but have yet to try it.

And as you are aware primers brand to brand and sometimes within brands have differing brisance. Misfires or poor ignition may be due to using a primer with lower spark energy. Who knows.
