[QUOTE="rotorhead, post: 127897, member: 5078"] I will touch on this one, You ask if the powder burn rate makes a differance... If I understand correctly the temperature that the powder burns and the longer it burns in the throat will predict the barrel life. So double based burn hotter and single base is cooler. A heavy bullet is harder to push down a barrel so the powder burns longer at the throat. If I'm right and I think I am this is how it works. You are shooting a 270 It will take alot of rounds to smoke your barrel. I think if you want a lighter round for pratice thats ok but I practice with what I shoot for real this way I can learn the rifle and the load and most importantly the point of impact at all ranges. I'm not real sure if I helped you or not I've only had a couple cup of coffee so far. RH [/QUOTE]
