130 grain bullets in 6.5 Creedmoor, AR 10 May 11, 2020, 01:41:17 PM i’ve been playing around with 130 grain bullets in my 6.5 Creedmoor chambered A.R. 10. I’m pushing for velocity and effectiveness between 400-800 yards. I have IMR 4350 and IMR4451 on hand. Would like to hear what everyone else is using in their AR 10 and see what recipes there are out here for me to plagiarize.
