Primer swapping?

[csburtch]

I keep seeing people asking if they can use SRP for SPP or many other combinations like magnums etc. Is there somewhere on this forum that would cross reference how they could replace each other with the exception of dropping to charge or increasing it?

I think there are too many combinations of brass, powder, primer and bullet to just have a compatibility chart.

That being said... I just rework a load if I change one of the components (I skip brass in pistol, since I use range pickups so I assume random and never am at/near max loads).

I have recently switched from SPP to SRP, for my major USPSA .40 S&W Loads. I now only stock 3 primers in my stash, SRP, LPP, LRP. My largest concern after seeing my chrono data, was to see if the "harder cups" on SRP would fire in my pistol consistently.
