18” 1-7.5 twist bead blasted - Alexander Arms AR-15 Barrel - Threaded, 6.5mm Grendel

I purchased this barrel directly from Alexander Arms about 5 years ago when building my first AR-15. After much consideration of barrels, this was my selection. Has no issues holding sub MOA groups with factory ammunition, I have hand load ladder rounds ready to test but haven’t had the time yet. I am interested in seeing what I and it can do with hand loaded 90gr Speer TNT, 100gr Barnes TTSX, and 123gr ELD-M’s can do. 260 yards with Hornady Black 123gr ELD-M produced a 2.25” group, .82 MOA.
