Is yours just the voice of experience or are you basing it on a published source? You don't say which in your post. I'm not questioning your accumulated experience, but it is one thing to have Greybeard #1 saying 3.5 is the max and then maybe having Greybeard #2 saying 3.7 is the max and having to decide versus having Gerybeard #1 saying that the concensus of Lyman, Hornady and Hodgdon is that 3.5 is the max.
