how much does a loaded 500 asquare round weigh with the 600 mono solid

About 1025 grains, depending on your load.

315 for an empty primed case (A-square brass)
110gr RL 15
600gr bullet

thanks very much I was guessing 1100

Yer welcome. Oddly enough I just happened to be sitting within arms reach of my 500 A-square brass and scale at the moment I read your question.

Interesting to note you only get 7 rounds per pound.

It's so funny that you asked this question. One of the first things that I did was weigh the ammo to determine how many rounds could be taken to Africa. I believe that it works out to a theoretical maximum of 68 rounds, if you take nothing else with you. It's about 2 1/4 oz per round.
