Anyone know where I can purchase either jacketed or plated bullets for my S&W 500 that are above 500gr? Looking to reload these so not interested in buying the finished ammo, just bullets. Tried reaching out to Ballistic Supply with no responses to emails.

I do not think there are any jacketed projectiles over 500 grains.

There are plenty of hard cast designs that go up to 725 grains. You can buy a mold and cast your own or find one of the commercial casters to buy projectiles from. http://www.mattsbullets.com/ offers 16 choices in cast projectiles for the 500 S&W

This old photo shows 450, 510, 550, 640, 650 and 725 grain solids. Since then I have added molds for 400, 440, 600 & 700 hollow points.



Here are some projectiles from the 600 grain HP mold
