I've had the same issue as JB. When I finished my 257 AI I bought a few bags of RP cases of the same lot, a buddy bought me some custom loads using RP cases, and I bought some factory-loade WW +P stuff.
The RP cases I bought as components have held up well, while the ones that came in the custom loads (these were standard Bob loads) have not. The former have had more loadings than the latter, but the latter have had primer pocket issues already.
I haven't loaded the WW +P stuff as much as the RP stuff so I can't comment on that.
Bottom line, RP stuff seems to be hit or miss...
