I'm looking to get a couple of these bullets in 500 S&W to compare to the Barry's that I have. My friend and I are looking to try to get to the max load for the Barry's and we are using the Speer data but we do not know the exact case volume difference between the Barry's and Speer. Willing to pay, just need a couple if anybody has some for sale. I tried in the classified section but no responses yet and nobody seems to have any for sale on the rest of the interwebs. Thanks.
