Got quite a few magnum primers to use.
Anything to consider when using with a .243 or .308?
Couple grains less as starting point? work up from there? Or are they unusable in .243? Would be with N160 and 85grn bullets.
I've noticed that some bulk .223 Remington ammunition can be inconsistent when switching between standard and magnum primers. In my experience, magnum primers can give a bit more pressure, which might not always be ideal depending on the powder and load you're using.
