Re: Finding max load for semi-auto .308
Max loads are available from the data that the powder manufacturers provide, but you don't want to run loads even close to max in that rifle for good reasons...
... and no factory high energy ammo, or heavy bullets either, because doing so will eventually batter the receiver rails beyond repair and trash the action. The 7400 is not a good rifle for experimenting with hot loads. It is a light duty rifle that is best carried a lot and fired mostly at game...regardless of what Remington says about it.
The loads you want to run are moderate loads of faster powders like 4895 and no bullets heavier than 180 gr.
Loads equivalent to Military ball, or Federal GMM Match ammo is as hot as you want to go. These loads are a couple of steps down from max, or what used to be referred to as mid-range loads in reloading manuals. The powder burning rate is very important. 150-165gr bullets work very well for just about any game, and no powder is better than 4895 for this application.
The good news is if you feed the rifle the right ammo and keep the chamber clean and the bolt greased it will minimize wear and tear and provide many years of service.
