Recieved word about the stabilization of the 500. The 1895 does shoot the 500 just fine. The thumper mold will be an iron XL double cavity throwing a plain based version of his standard 500gr bullet. Ill be testing it as soon as I get my paws on it.... can't wait.
I decided to get this mold because of the big meplat (75%), I considered an RCBS but it has a tiny meplat (around 60%) and a gas check. I don't plan to shoot the bullet fast enough to need a GC and they add extra expense.
