Re: .308 warbird questions.
Probably a good chance factory Lazz. stuff wouldn't match up exactly to what's listed on the box. He'd be developing loads using a 27" barrel with a tight, custom chamber. If you're shooting a factory rifle, you'd be using a 26" barrel with a chamber held to lessor tolerances. No guarantee that you wouldn't meet advertised fps, but it would certainly stand to reason if you didn't.
Using whichever bullet you chose for the round, if you use Retumbo, I really don't think you'd have trouble reaching (+/-20 fps) advertised performance quotes.
That Lapua I shot was a while ago. Felt recoil was somewhere between my .25-06 and .270 loads, as I remember it. Don't remember the specifics on the load used (50 developed the load) but it was real manageable.
