[QUOTE="dougm, post: 317606, member: 5372"] Well the .338 Lapua is doing well. The Barlein barrel is breaking in nicely and my speeds have been increasing steadily. I have about 150 rounds through it so far. Here is how the velocities are at this time with no pressure signs but I do believe these loads to be close enough to max that I'm not going any higher with these bullet/powder combinations. 225 Barnes TSX tipped pushed by R22 is yielding average speed of 2892 fps from the Lapua's 20 inch barrel 250 Scenars driven by Retumbo gives average velocity for 100 gr's = to 2927 fps and for 99 gr's gives 2902 average speed. Accuracy is about .75 @ 200 yards from a bipod off the bench with the 99 grain load and just over an inch with the 100 gr load. The R22 is giving me excellent accuracy with the 225's but I'm sure I can get better speed from a different powder. I should be able to get close to 3000 fps if I tinker with different powders. Now for the new build. Going on the premise that you just can't have too many .338's I'm going to build a lighter weight (around 11-12 pounds) pistol in .338 Norma Magnum. After reading the threads at Snipers Hide and the wonderful article here on Long Range Hunting I'm sold on the cartridge's efficiency and accuracy potential. I'm going to base it off an xp action and Benchmark barrel. I have spoken to a gunsmith who has built several of these on Rem long actions without issue. We will see how it comes out. Hopefully it will be ready by early spring. Doug [/QUOTE]
