Right on! I've tried N570 and it's very hard on barrels due to extreme burn temperatures. I found out the hard way, but luckily had several other barrels chambered and ready to go. I'm back to Retumbo,RL-23 and 26.If you’re burning N570, don’t expect the barrel to last the longest. I’m burning retumbo in mine. It’s way cleaner and doesn’t eat barrels. My 1st Max barrel had noticeable cracking a and erosion after 250 rounds.
ill give up a few FPS for a cleaner and cooler bore.
