this is similar to what i just went through and i can't decide against the lapua.some get 3000 with a 30" tube but most are between 28-2900.don't know if a titanium reciever is strong enough but would be a good start.barrel contour/length and stock will determine your weight.i'd say stay at least 12 lbs with the gun and loose 5 pounds of weight and you'll be able to walk farther!
I have not worked up but a few loads many but Speedy built mine and it started as an Accumark 30-378 and is now a 338 Lapua AI. With the brake he builds and I have fire formed 100 rounds(98 gr of WMR with 250gr mk's because I have a lot of them left over from my AIWM 338 rifles) recoils like a stout 30-06! My competition rifle for this year is a switch barrel and 1 of them is going to be a 338 Lapua AI as soon as the Broughton blank gets here but it shipped today. Another thing to consider is a fire forming barrel--the blank shipped today for that as well--thanks to the guys at Shilen who helped me with that. No reason to use precious barrel life to fire form which is a necessary evil in the wildcat game for the most part.
A lot of trouble to go to when the 338 RUM is out there but hey that is what makes this game fun!!!

Jim & Hoss, can i ask what advantage an AI is over the regular lapua. are you getting more than 50-100 fps? will that make any difference in anything.now that seems like a lot of extra bother for very little.of course that's what makes this fun!
I agree that any 338 round capable of driving a 300 gr bullet to 2800 fps or more is more then enough for any critter on the planet really, depending on bullet design of course. In fact you can get by with much less.
Easiest option would be a Lapua or 338-378. The Lapua Improved or Kahn will both offer about the same advantage over their parent cases, around 100 fps in a portable length barrel.
If you are not favorable to the Wby double radius, the Kahn is a great round.
The Sako is a fine rifle, with a recoil lug upgrade and restocking it would make an impressive long range hammer in any of the 0.590" bolt face rounds.
May I also add that you really need to get some of the Wildcat 325 gr 338 bullets. These are flat base bullets that are ment for big game. A more potent big game bullet would hard to find. Richard is mystified why this big bullet is not a better seller, me to!!
If your shooting something in the Edge class or larger, you should really look at this bullet. Let me know if your interested.
Basically, a 9 lb Kahn is alot of rifle but properly designed, not more then you can practically handle and its authoritative hits on game would be impressive.
Also, do not think you need 30" of barrel. No need in this bore size, you will not gain alot of fps per inch of barrel past 26 or 27" of barrel length. I would go with 27" with brake and keep the barrel stiff and rigid. Oops, should not have said that, will start another arguement [img]/ubbthreads/images/graemlins/grin.gif[/img]!!

To answer your question--I do not know yet but I expect to get a 300 gr MK going right at 3000 or a little more using the 5C Broughton. This is going to help me with the wind and my problem judging it. I am going to use the 250 gr bullet with the hunting 338 Lapua AI just have not had time to really fool with it yet. The AI version (Dave Kiff did the reamer) and it is giving almost 7% more capacity over the parent case.
Is this worth it---you be the judge but I like to be different and Speedy and I are discussing building a version of his ultimate seating die for this but to tool up for it will be BRUTAL cost wise and to top it off no one builds an Arbor Press tall enough to use this die if we build it so an extension will have to be built for my press—oh well it’s only money and time!! Anyone want to send me some of both?????
