[QUOTE="J E Custom, post: 471113, member: 2736"] For a hunting rifle barrel life is not that big of a deal because of the total rounds fired over many years. And any of the big 30 or 338 mags are tough on barrels compared to a 308 win class of cartridge. Weatherby brass is made by Norma and with good loading techniques can last a long time. The 338/378 will out do most of the 338s with big bullets and this would be the obvious choice for the rifle. (No mod required). The next choice in my opinion would be the 337 Lapua Improved . It is not as powerful as the 338/378 but is a fine performer and has very good brass. The 338 Lapua has a head diameter of .588 compared to a 338/378 Weatherbys .379. The bolt face can be opened up very easy (.009) and the Same extractor will work with with the Lapua case. The flat top follower and center feed in the 338/378 works perfect for the Lapua also. All of the rum based cases have smaller bolt faces and need to be modified or replaced with a standard Mag bolt face (.534 Dia.). J E CUSTOM [/QUOTE]
