That load won't fill a Remington hull anyway, the crimps will be dished to the point they leak shot.
Nitro27 hulls are in the recipe from Hodgdon, and are what I have a thousand of. I need to use them up, and then I can switch hills.
Hodgdon lists no 7/8 ounce loads with 700X, which is what I was referring to since that's what you asked about.
There are a great many loads listed by the various powder companies that are impractical, and since they can't test every possible combination there are undoubtedly some that would indeed work fine that are not liasted.
A 7/8 load with the CB-1100 and 15 gr. of 700X is a piss poor choice and either they tested it and found that out, or they had the sense to not even try.
