I'm trying to develop a load for deer hunting with my AR-15, and I could use a little advice. I have some 60gn. Nosler Partition bullets and I was wondering if anyone out there has tried to do the same thing I'm attempting. The gun I have is a Colt Match Target Competition HBAR II. Its got a 16in. barrel with 1x9 twist. What have you guys found that works well? Thanks!
