The lighter bullets seem to really shine out of 6.8 SBRs. 110 is light compared to a lot of .277" offerings, but there are bullets as light as 85gr available.
I love the Federal XM68GD 90gr loads in my 12.5", and I'm trying to get my hands on some of the Speer 90gr TNTs to load up for it.
I just bought 200 rds of the Federal xm68 I've just been trying out a lot of different stuff. Once I got enough brass I'm gonna have chad load me up some 90 gr hollow points.
