So what your telling me is the guys that shoot 147gr with Rl26 out of a creed is ok but not 3 k with a 97gr out of a grendel.Heres the deal. Brass will not show pressure signs until 70k. So reading primers on a case with saami at 52k is pointless. In a bolt gun maybe. But not an ar.
And I'm not reading just brass, primers are made of different materials and have been used to read pressure in ar for a long time.
And velocity is one way to read pressure not the only one. He ace why Weatherby can gain 200 fps over chambers without the freebore.
I get it you don't wanna believe it can be done. So don't try it but telling everyone who has come to the same speeds with said bullet they are all wrong and not loading correct is also stupid. Almost everyone on ar15 and this sight does not have real pressure testing equipment so we go by what has been done for years and it's proven safe over the long term. So I'm gonna keep doing it.
Hammers require a much faster powder to get those speeds. So yes they create less pressure which allowed faster and more powder
. By your logic of velocity being the measure everyone running hbn bullets to gain speed and add more powder by reducing friction is not actually reducing friction they are juts over pressure which somehow magically hides all signs of pressure they normally look for.
