Pressure conserns legitimate or my imagination?
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.
As to 215's in a 300win, it is all I will use as I hunt with it and it needs to go off when I pull the little lever on the bottom. I hunt in nasty temps some years, and if I'm over 70 gr of powder I won't use a standard primer even if the load is more uniform. I don't have a pet gorilla to drive the bullet out if it squibs on me, so I hit it hard to start with. Don't think a squib will never happen; I've seen it with both shotgun and pistol with listed loads when the temp. gets cold enough. It's a bit easier to drive a bullet(or wad) out of one of those than a 300 win so I don't fool around.
