Thinking about ordering a 308 gradous barrel for my AT and seeing if anyone has one and what you are using for loads. My factory 1-12" Lothar is fantastic but I'm opting for more length and a 1-10" twist at this point.
I don't know about Gradous but it's hard to pass up a Patriot Valley Arms prefit for 15% less. That's where I'm going for a 6.5 CM for my AT...someday.
Of the people talked about here with regard to AI barrels, you cant go wrong with any of them. PVA, mile high, Stuteville, gradous. There are a few others.
I have Gradous 6.5 cm and 260 26 inch barrels which both shoot lights out. My AI factory 12 twist 308 26 inch barrel shoots just as good. I don't think you will gain much by replacing your factory 308 barrel with an after market 308 barrel...Ray
I have the Gradous in 308 and have over 2000 rounds through it in about 7 months and it still holds sub 1/2 groups when I do my part. When its time to replace it will be one of his barrels.
