He's made six for me, and I've just ordered two more, one for a 6.5X47L, and a 264 for a Curtis Customs Valor PRS rig.
He's not a factory. He's a craftsman, a machinist, and the same guy on the phone as the one making your barrel. He makes first class bench rest quality barrels, from billet blanks, and could probably charge twice what he does. If you barrel is taking months, he's either in the hospital, or has a stack of savage prefits in the cue for guys who have no idea how lucky they are to be able to plink at 100 meters with one of his barrels.
Place an order for one for next summer now, you might get it in the fall. Can't wait? Go get a prefit from IBI or Area 419 etc.
But eventually, you're going to want one.
