I ran 1500 rounds through a 700 chambered in 7.82 Warbird. Now that 700 is chambered 30-338 Lapua AI. As far as my own use, the Lapua case in a 700 doesn't cause me concern. With that said, I would still recommend the 338 Edge, or 338 RUM. Less hassle, brass can be found, and a greater safety margin for those that need it.
My 338 Edge wears a Broughton 10 twist, 5 groove, 30" and a Ross Schuler brake. I have been pushing 300 gr SMKs, at 2850 fps, with H1000 since it was put together, and I have no need to change. I haven't seen any advantage to going faster than 10 twist, but there really isn't a downside to 9.7, 9.5 or 9.3. I'm expecting to see 2K rounds without the need for a rebarrel.
