I have a few questions regarding the 2 primers. Is the 210m strong enough for the 300 WM? and (ON AVERAGE) what is the velocity difference? Ive heard some people say that the 210 will be more consistant in velocity?
The 210 m will probably give you better standard deviations that the 215 .
The 215s work best on cartriges that use 90+ grains of powder because they are hotter
but on smaller cartriges they will cause the ES and SDs to be greater than the 210s normally.
So I would recomend using the 210 m and if not satisfied then try the 215 but reduce your
loads and work up.

If you start at bottom listed charge you will be alright, but a 308 win is a bit small for a 215 unless you are lighting ballc2 or similar.What's es and ds?
I got 215 primers for my 308 and was questioning if it was overkill (pretty sure it is) but more afraid of too much pressure since I just read Lee recommends using slower burning powder with magnum primers I'm using Varget.
Pressure conserns legitimate or my imagination?

It depends on the powder and what you are using it for. It's not "redneck wisdom". There is a method to the madness on this.Thanks I'll look into this.
I have some telling me 215 is fine for 308, but I want real science not redneck wisdom so I appreciate the help.
