When my brother got his Warbird, same as the one you are playing with. He loaded up to Lazzeronis recommended load with RL-25 and this was from actually speaking with him over the phone. He said the Sako will get 3500 fps easily.
Well, my brother loaded right up to 3500 fps with the 180 gr pill with RL-25 and was pretty happy with the results. Around 3/4 moa average. When he went to reload them though he got a little sick to the stomach, he had blown the primer pockets on over 30 of the 50 cases he had loaded up.
Lets see $2 a pop times 30, well you get the picture, not happy camper. This was about the time Retumbo came out. We worked up a bit more cautiously with this new powder and I will admit that his top end load did average 3505 fps but was still a very warm load.
Personally I would have loaded to 3450 and left it there but he wanted 3500 fps. Rl-25 will loosen the primer pockets at this level which is good for Lazzeroni, you need to buy new cases after every shot!!! [img]/ubbthreads/images/graemlins/grin.gif[/img]
The Warbird is a fine round but Lazzeroni did not do it any favors saying it will match or exceed the 30-378. In all honest, if you look at the case capacities, it is much closer to the 300 RUM then the 30-378 and its performance levels also reflect this.
It will get you about 50 fps more then the RUM in same length barrels and about 75 to 100 fps less then the 30-378 in a 26" class barrel. Still the top of the pile in "factory" 30 cal rounds but not what he advertised.
His velocities, like all other factory loads are developed in tight chambered match barrels. Put them in a Sako with a factory bore and chamber(although they are generally better them most factory chamebrs) and you loose velocity and often a significant amount!!
Like you said though, do not believe the print. It makes a guy a bit mad when he pays $90 for 20 rounds of Warbird ammo only to get sub 300 Wby performance!!!

What the heck......no magic carpet ride?? Case capacity DOES DICTATE velocity?? I'll be darned. And what about all the guys posting on the internet that their "stock" rem 300 rums are running 3500 with absolutely no pressure signs!!!! Ya right.
