[QUOTE="Steve Shelp, post: 21061, member: 22"] Joe, To give you a base line to go by I shoot a 338 Lapua Improved through a 32" barrel. this case has 120.5gr of H20 for water volume and I can go over 3000fps with it. 2900 is easy without pushing it at all and is where my accuracy load falls. To give you a comparison the 338 Ultra Mag volume according to some others on this board holds 113gr of H20 and I believe Remington is making them with 26" barrels. Some others here have volumed the 300 Ultra and have come up with 116gr I think. So lengthening your chamber will give you more case capacity and end up somewhere aaround the 116gr mark, but the 26" barrel is going to hinder you some also. But you might be able to reach 2900 though. if not your going to come darn close. Hope this helps. Steve [ 08-27-2001: Message edited by: Steve Shelp ] [/QUOTE]
