Magnum primers for .308win

[McSnipsy291]

So I have a few questions about primers first off I am running an AR-10 and using Fed-210 primers am I asking for a slam fire? Secondly if I switch primers what would the effect of magnum primers be.. (190gr bullet and imr4320 powder)

Would magnum primers shift my pressure curve slightly? Is there a chance of possibly igniting more powder initially and increasing the dwell time at peak pressure to gain velocity through efficiency or am I just going to spike pressures and have to reduce the load to keep from blowing chunks of bcg through my magwell? The load I am running is not hot as I have worked my down in a hunt for accuracy and I dont want a hot load but I am always down for efficiency and I am a nerd for ballistics technical knowledge.

Any harm in trying magnum primers for .308?

You are less likely to have slam fires, magnum primers have thicker cups.

LR primers have the same cup thickness. There is no difference in slam fire potential.

I am not asking if magnums will be less likely to slam fire. I am curious how they affect the pressure curve. Do they tend to shift the curve or just all around increase pressure

I am however curious if fed210s are inherently risky with slam fires... I should have been more clear that the two topics are not directly connected

I have used WLRM primers in 308Win with no ill effects but not ideal outcomes. In given charge weight mag primers gave about 30FPS more but the ES/SD was higher than std primers. Mid-range loads so no pressure issues noted from a bolt gun.

They are not.
