My latest project is building a varmint rifle for prairie dogs to go with a scope I picked up (a 6.5-20x).  I am looking for a a source for an accurate 24' stainless barrel (hopefully in a 1/12 twist).  Most vendors have the 1/9 or 1/8 barrels for shooting the heavier bullets and they seem to mostly use Wilson barrels.  I am not real keen on the heavy "bull barrel" contour.  They seem to make the rifle too muzzle heavy.  

Thanks for the help.

You can buy a cut rifled Oly Arms barrel from [url=http://www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=12471]Brownells[/url]. They are a 1/10 and very accurate. I am putting one on a project I am building for my wife.

Hi! Although it is Heavy, I went with the Heavy Bull from RRA, it is 1x12 and Stainless and made by Wilson. If you can't do better you can always have it turned down to suit your needs. i really like mine, very promising at this point in break in with 55 Nosler Ballistic Tips.
