Hello everyone! I’m Tanner and a new member to the forum. I’m looking into building a 7 rem mag and not sure what barrel contour would be best for me. Some guidance would be appreciated. My 338 edge’s are a little heavy to be packing around anymore. I like the heavy barrels but not the weight. I’ve thought about a proof but I’m skeptical if they are better than a plain steel barrel. I want something that can handle a few shots and not heat up like an ultra light thin pencil barrel. Something packable yet I can smack some steel with my buds and not have to worry about my shots walking after a few rounds. Thanks for any input!
