[QUOTE="Timber338, post: 1042902, member: 33822"] So one of my hunting buddies owns a semi-custom 338-378 around a Weatherby Mark V action, but it only has a 26" pac-nor barrel on it. He has finally gotten around to realizing he wants a true ELR elk/bear rifle and is looking to getting a really long heavy contour barrel... something on the order of 34-35 inches long plus a brake. And shooting the Berger 300 grain Elite Hunter. I wanted to see if anybody out there who has a rifle like this could pass along any advice? I've never loaded for the 338-378 so what are the top powder choices? My guess is that H-1000 would work, maybe RL-33? Are there other powders that are better? Are there any pitfalls to an ELR build around the 338-378? Dan Lilja wrote a great article where he started with a 46" barrel and collected velocity data while he continued to cut the barrel down in 2" increments.
