It only hurts for a little while.
W120s were my standard for .270 and briefly, the .243. F210M were for .308 loads. I never got into my supply of the new W120s, and picked up a bunch of regular 210s and now a brick of BR2s. BR2s and R15 have so far been the stars for my current .308, so I'll probably stick with them. Unlike the 210Ms, they can usually be had, at a price.
Gotta wonder if the generally better availability of CCIs is related to the fact that they are less of a presence in the CF ammo market. I've read that the primers we get from the Big 3 are the leftovers from ammo production and given the situation in that market, they have fewer leftovers to sell as components.
