For those who have either had custom jobs or built you own and have had poor results with it? Ok, you now installed a barrel on your trusty rifle, worked up loads, tested.........and results were less on the lacking. You might have had/made a choice from a suggestion of a friend, internet research or maybe a 2nd barrel from the same company? Some are new popping up every year and some a few decades old? What gets you coming back or just leaving those mfgs? These choices can be on AR's and/or BA's on your experience. Aero Precision was new to me when I was looking for a 6.5creed barrel (not a build from them, only a barrel purchase). They had 3 in stock and was going to ship it in the next 3 days. I got busy and haven't checked on the order in 3 weeks. Gave them a call and a reply was "the accuracy wasn't meeting their guidelines". About the 6 week mark the barrel arrived. Installed the barrel and WOW what a shooter with factory ammo nun the least. I've built over 50 AR's in 10's and 15's that have had several different cartridges for them. I have PR, CBI, Faxon, BCA, AP, Rosco and a few others that haven't failed accuracy test. Now I'm on to BA's. While the 2 in building stage are 110lam actions for 300wm (C6 30" 9T magnum profile) (McGowen barrel for C6) and 264wm (McGowen 32" 7.5T savage magnum profile) I'll see how they stand up. Some might have a reputable name, but get lost in quality or accuracy? What are your experiences?
