I just recieved my 338 Lapua that I had built on a Rem 700 action, with an ABS carbon wrap barrel that is 31" long including the brake, set up with a Seekins Detachable box magazines to take a 3.9" COAL, set in a Rem. Sendero stock. I originaly wanted to shoot the 325 grain Wildcat rebated boatail bullet, but it will not stabilize in the 10 twist of my barrel. They were key holeing even with velocity over 2700 FPS. Today I tried some 250 grain SMK bullets with 98 grains of H-1000 they averaged 3189 FPS with a SD of 11 FPS and 95 grains of Reloader-25 averaged 3197 FPS with a SD of 9. I also tried 98 grains of Retumbo and this load averaged 3010 FPS but seemed a little mild in the pressure department and di not shoot nearly as acurately as the other 2 powders did. Next I moved back to shoot a group with both loads to 330 yards according to my lazer range finder. I only had 2 of the H-1000 loads and the 2 shots went .634 inchs. The 95 grain load of Reloader-25 with 3 shots went into a group of 1.125 inchs with the first 2 into .424 inchs I was very pleased with this performance both in the velocity and accuracy. Tomorow I am going to shoot some more with the H-1000 load.
