Not using someone else's loads is a crock. I have several friends that I trust completely and I also shoot factory ammo.
News flash, if you are shooting factory ammo, someone/something else loaded it. I don't have friends that are retards.
Inever not ever start with a load someone else worked up unless it's well under max. All that factory stuff that's different has to be loaded to some standard we don't know about. Reason being we haven't a clue about the rifle or chamber it was worked up in. I suspect most factory loads are loaded to less pressure than they will admit. reason being the put out a bunch of bad stuff and it blows up some guns, they are liable! In most case's I doubt it matter's to the factory's that their loads may be light as handloader's seldom use factory ammo and non handloaders don't have a chronograph!
