First, I would weigh a bunch of these bullets to figure out what “more weight variation than normal” is. Heavy bullets at max charge can add to pressure. That said, they would have to vary by 5gr to sweat it from a safety perspective.
The max on a powder jug is very generic data. You need better data. Yes, you can generally group bullets by weight and construction. To discuss what max means, we need to think about how guns fail.
Guns generally are evaluated in some kind of a fatigue scenario. This means that a gun can accept much more pressure from a single pressure event vs continued use of over pressure loads.
When you see blown up guns, this is not a slight overload, powder measure off, etc. It is a long life failure(fatigue limit), bore obstruction, wrong class of powder, component degedation, etc situation. That said, if you make a habit of loading over book max, your gun will fail at a much lower round count with much more sensitivity to primer changes, bore dirty, crappy brass, etc.
So from a safety perspective, the +/- 0.3gr that almost every powder system can do is fine. If we’re talking 25 auto, 32 auto, etc, maybe we need to use a fine powder to get back to +/-0.1gr. You do need to check your system regularly. A system can clog or get static causing wild variations. You need to make sure that is not happening.
Another thing not clear in most reloading instruction is the importance of OAL on pressure. OAL can greatly affect pressure both in distance from touching the bore and in seated length. While different, they cause the same thing. Shrinking the burn chamber size or slowing its rate of expansion both cause pressure spikes which can be sizeable. So you have to set the OAL to be safe and functional. Some semi-autos are oal sensitive when feeding. You also need to hold that position through the rounds handling by you, the mag, the feed cycle, and previous firings/recoil.
