[QUOTE="Max Heat, post: 632124, member: 43153"] I'm upgrading my Savage 110 7mm rem mag to a heavy stainless 7RUM barrel, and I shoot mostly light bullets (120gr Nosler BT's) that I figure will be sent out at well over 4K, using the maximum powder charge for the RUM. I'm prepared to accept a relatively short barrel life, but I have heard some say that double based powders such as Alliant (I've been using RL-19 in the mag) burn hotter, and therefore will erode the barrel faster. Is there any truth to this? [/QUOTE]
