Saving 100.00 on a barrel is silly when it's the most important part of a accurate gun and a small fraction of the cost for a custom rifle. Cry once and be done IMO.
Seeing how you are not going after the pre-fit benefit this is exactly how I feel. I like cut rifles for custom chambering, but Greg Tannel chambered a .300 Lapua in a Lilga 3 groove I owned that was nick named the laser beam, excellent barrel.
