[QUOTE="IdahoCTD, post: 1048405, member: 13110"] I don't own a 338 Lapua but I have built a couple for other people. I have all the parts to build one if I wanted one except dies and could have it together tomorrow if I wanted one. I already have a 338 Edge, 2 338 Baer's and had a 338-378 Weatherby I built when Sierra came out with the 300gr SMK's nearly 20 years ago. In 30 magnum's I have a 300wm, 2 30-8mm's, 1 308 Baer, 2 30-338 Norma Imp's, a 30-378 Imp, and a 30-338 Lapua Imp. I've also had a few 300 RUM's and 30-358STA's. I've got a pretty good grasp of what things are capable of and case capacity equals velocity provided pressures and barrels are equal. I actually measured the 338 Lapua case capacity with a new case and I measured a unfired Edge case at 113.7grs. A fired Edge case is 115.9. Swamplord posted that the 28/26 Nosler cases had 100grs of water capacity and on my scale a unfired 7 STW made from 8mm Rem Mag brass is 96.7grs. So yeah it has a couple more grains of capacity and that would amount to less than 50fps. It's not magic pixie dust stuff it's velocity based on case capacity. If you want to talk about efficiency, one of my 7-300wm does 3260fps with 162 Amax's in a 27" Schneider barrel with 73grs of H-1000 in RWS cases and the other is a 28" Benchmark and does 3290fps with the same load.
