New to reloading, but looking at the Nosler #7 manual and the 257 Roberts Data. No indication if that's for +P or not, is it?

If it's for the standard loads, where would a person start out at if looking at the same data for +P loads?

I believe I've got a load for a rifle I bought that calls for 46g of H4831 & 120g partitions. But that's 3.5g over max according to that book.

Thanks for any help.

Life is just one damned thing after another
