.500 S&W Crimp Issue

Hello,

Does Dillon make a Military style crimp for the .500 S&W? 

I have used the Lee roll crimp and then ordered the Redding Profile crimp die with no real luck with either on holding the bullets in the cases after shooting 3-4 rounds the last round is usually out of the case 1/32-1/16  and I can see the crimp mark in the canalur, the redding die gives me 4 good consistance loads, but he last one is usually much lower velocity, Lee only gave me 2 rounds before they all began to creep out. 

I'm using Berrys 350gn double struck plated bullets, any help would be great!

How fast are you trying to push the bullets? With the plated bullets, keep them under 1200 fps. We don't offer any alternative crimp for 500 S&W.

Berrys told me they have used them out to 1800 with no issues, I 'm currently loading H-110 at 40gn = 1420 FPS, I know lee makes a custom die for "factory crimp" but will take 8 months on back order.
