It is a matter on testing the rifle and seeing what works the best in your powder,case and
powder grain amount.
Often a standard primer lowers the Standard Deviation in magnum cases but does not
lower the velocity by very much.
The standard primer can work well in magnum cartriges under 90 grains capacity with some
Cases that have a case capacity of 90 to 135 grains normally do not respond to the standard
primers well and need magnum primers.
So it is a case of how much powder, what kind of powder and bullet weight.
The 7 STW is about the max that I have found that in some cases responds to standard primers
I have not seen larger cases respond well to them. others may have different results.
