195 Berger in 7 prc

[highfinblue]

I couldn't get the velocity until I got to n570. H1000, retumbo, or whatever else couldn't do it.

it's amazing powder, I shoot it in my Nosler, but they say it burns hot and shortens barrel life or I would use it more.

I use it I'm my 28 as well. 568 is good as well

I've not been able to find any 568 but did find some 570.

You are definitely not the majority. Very impressive for a prc for sure. But your statement is not quite true. The 7prc and the 7rm are not basically the same except for a belt. What would be more factual is the the 7RM and the 7LRM are basically the same except for a belt. You are an exception to the rule essentially. Not to be ignored but also not to be expected. Your 7prc performance is not what people build a 7prc for because it is categorically not going to produce the numbers you see. At least it categorically has not. So your findings haven't quite put this to bed like you'd hope. But impressive non-the-less!

How are they not? They are all very similar case capacity. The 7 LRM and 7 prc use the same parent case, and have almost the same case capacity. So….

From Ammoguide (because no one will agree anyway)
7mm PRC 79.5
7mm Rem Mag 80.8
7mm LRM 84.8
7mm STW 92.7
28 Nosler 97
7mm RUM 106.6

Y'all can "similar capacity" or call all that BS but it is published numbers. I'm good either way.

Not saying they are false, the velocities referenced in some posts are exceptional numbers. Unfortunate for me that no documentation I have, nor QL can make it.

I'm sorry but your comparison hardly accomplished what you thought it would! Just sayin....
Impressive that your 28" prc put out astonishing numbers but those numbers are not astonishing for the cartridge you are looking to best. Fact still remains that the 7prc struggles to keep up with the numbers 7RMs put out. which is not surprising being that it has less case capacity.
