Wow, that's really all I can say.....
Brian really is becoming a used car salesman.:nuts:

"In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve
greater velocity at the same pressure than a cartridge with a bullet seated short."

So if we load a bullet much longer, then the net result is that we get to use more powder for the same pressures? Yes Brian, we all remember the arguments on both sides for the 30-06 Vs. the 308.... The reality is that in 308 sized cases, the change in case volume for seat depth is really irrelevant. The change is not significant enough to concern yourself with, when used in most all factory guns.

And his claim that all cartridges are ballistically "limited" by SAAMI COAL??!!! Brian, you arse... SAAMI is a voluntary program only, and you know this. And EVERYONE has long known that bigger cases(take the 30-06 Vs. the 308) will push the same bullet faster at the same pressure... Because of a problematic Ogive, is why Bergers have long been suggested to be jamed in the lands in the first place.

Secondly, the REAL reason that one should want to be able to push a Berger bullet faster; is because Litz's bullets don't survive the Trans-sonic barrier at all. They are cool and slick when super-sonic, but if you want to shoot beyond that; you DO NOT want to shoot Berger.
