Just trying to come up with a comprehensive list of Good Long range bullets for the 338. So far, I have experience with: 250gr Berger - Advertised BC .682 - bullet ogive won't let me get close to the lands and still fit in the magazine. 300gr Berger - Advertised BC .818 - same problem as the 250 for me. Loaded some single shot an got decent groups. 285gr Hornady(Amax) - Advertised BC .720 - This is the best load I have found so far. I can get the bullet right up to the riflings. Shot about 1/2 MOA @ 300 yrds, if I am remembering correctly. If you have any other 338 bullets that you have experience with please share. Especially if you calculate the BC to be different than advertised. Now, I really started this thread(before I realized I was also curious about everything else too) to see if anyone has tried the GS Custom bullets in the 338 Lapua, and if their BC really is as advertised. A BC of .972 seems really high for a 267gr bullet..
