[QUOTE="WeiserBucks, post: 2105886, member: 97492"] Mine was throated for 230s and after the barrel broke in was making 3100 FPS with them using N570. Understand that it was likely a fast barrel and most won't reach that velocity safety. Anything sending a 230 over 3000 FPS is going to be a great performer, don't get to excited about pushing it super hard. My last barrel was luckily a very fast one but many will settle in around 3000-3025 or so with the 230's, Lapua brass and N570. Norma brand brass shows pressure at 3000, hint, hint. Most of us are over pressure with the stronger brass and don't even know it, proceed with caution. [/QUOTE]
