Let me ask you this. Why would you want to determine what the max loads are for either bullet when you have the loads from the loading manuals in front of you? Those listed are what your max load is. Out of the 30near loading that I load for myself and others, I cant think of 1 that shoots a load that is listed at or even near the max load. I have found in my 40+ years of loading that most weapons are going to reach their accuracy potential in the 2/3rds-3/4qtr throttle range. All the max loads do is what I call the 3W Killer. Kills your weapon, your wrist and wallet!!!! How are you going to determine what the max load your weapon can handle, it blows up? Plus, the animal does not die any faster or deader!!! And once you find a load that groups consistently without blowing your gun up. Why not just load that particular load and not have to remember where other loads will print. 1 load, 1 ballistic chart to keep track of.
