I use 98 grains of RL33, Federal 215 GM primers in Lapua brass with 300 grain Berger OTM'S. I get 2730 to 2760 fps out of my 26" barrel, and Quickload is spot on. I should mention that I also have throated the barrel to allow an OAL of 3.937" with the bullet .010 off the lands. It is a stout load, Quickload shows 62,950 psi and I believe it. Cip psi is 60,916 psi so it is over CIP pressure, but the original Lapua design was for 65,000 psi. British snipers regularly use "over pressure" ammo in their 338 Lapua AI's. Lapua brass is strong and I have never had an over pressure problem and have fired 800 plus rounds of this load. The case heads have a witness mark of the ejector hole, but not pronounced. I have very good accuracy too, 1/4 to 1/2 moa depending on how well I do my part.
