Is there really any reason to load a cartridge to its absolute max?
I have manuals from Speer Hornady Nosler and others and they all differ. I pick a manual with a load the gun likes, and stick to it (not always the hottest load) The bullet company's have the expensive pressure barrels and measuring equipment and they use it. I don't ,so my pressure gauging is only guess work . The bullet and powder company's have to err on the side of caution with there data and we should to. When you make a 1 grn. mistake with a mid range load its not a catastrophic failure, with a max load it can be. I have a 221 fireball case that will take a large rifle primer now because of a 1 grn.over charge, had to beat the bolt open.I pulled the remaining 19 charges and all were 1 grn. over. Any gun can be destroyed and none of us are above making a mistake ,so I will err on the side of caution too.
I only have two eyes and two hands and would like to keep them all. Modern Reloading by Richard Lee has some excelent reading on pressure chapter 7 thru 9 (second edition)
