[QUOTE="Brent, post: 25179, member: 99"] Tim, As far as I know neither Lapua or Norma make brass for the Ultras yet, one or both of them do however make brass for the 300wsm. My dad has a 300wsm and is getting 3250-70 fps with a 180 Ballistic Silvertip and 178 A-Max and just barely over max load at 65-67k psi on the Oehler. It's only a 27.8" tube as well. My 300 Ultra is getting the same velocity at the same pressure with a 26" tube, you be the judge, I'm using 95gr and he's using 72gr to do it too. I could gain 50-100 fps if it was at his length, maybe, maybe more if it 32 or better. Something to consider being as you can get good cases for it. He is at max powder capacity in this case and it appears to be burning most of it so how much can be gained by the extra length at 32 or more might remain to be seen, the 300 Ultra will make use of the extra length for sure.
