I have to agree with all you guys. I'll throw in my 2 cents worth. I'm not afraid to go over max with special care and attention.Have several loads that are over max and work just fine. " BUT", Had a 257 wthby was playing with. New bullets and powder with no load info. Started out low and just started banging watching for signs of pressure. Usually flattened primers are the first. The first signs of over pressure on this setup was swollen primer pockets. Loaded a new primer and it just fell in. There was no flattened primers , hard extraction or any other signs of high pressure.
Had another rifle, Ruger 30-06, was working up a load for, started a couple of grains under max and in this rifle that turned out to be max. Flattened the primers hard.
So you just never know, Be careful and know what to look for. If you don't get some help.
