Maverick, I'm fired up! I just talked with Bobby of Freedom Gun Works - great guy and took a lot of time explaining everything to me!
They build them from scratch, from chassis's on hand, so no need to buy a barrel you don't need. $2,560 for the chassis & bbl extension, and $1,500 for the bbl and gunsmithing & shipping, give or take, depending on your choice of bbl options.
He says that his 7 WSM shoots into "the teens", and he's won a 1K yard match with it. Sounds like a real straight shooter too. I mean, honest.
They will do any caliber and twist rate you want. So, planning now to thin the herd greatly and raise cash to obtain one with a 28" bbl in 7 WSM, .280 Rem, 6.5-284 Norma, or 6.5-'06 A square, with the melonite bbl coating ($100) and spiral fluting on the bbl ($160). He says the melonite coating will at least DOUBLE the barrel life, so it's a steal at $100 for a barrel burning caliber. PM for more info. This is gonna be my long range gun I've been thinking of for years, I think.
Oh, and they have to use the .300 win mag bolt and magazine for the 7 WSM, due to bolt face size, but he assures me that it feeds flawlessly from the longer mag.
On bbl quality, I believe that they guarantee 0.5 MOA - but I forgot to ask him who he has do their barrels for them.
Get a load of this - this is Bobby:
