I know a guy that shoots one. It is accurate out to 600. Probably beyond, but our range only goes out to 600. It is a good cartridge. Downside of the cartridge. Quality of brass is a concern. I am sure that Hornady brass is alright with good prep, but its not lapua. The cartridge design is good in the larger framed ar platform. The downside of the dpms package. The trigger is awful. It needs to go to bill springfield or have the trigger replaced. I like to shoot prone. I don't know about you, but for prone shooting a prs stock or equivalent is the way to go. Other than that its a solid platform and should be a nice rifle.
I recently acquired a 260 rem. in the dpms package. I have shot it very little since purchasing it. This is how I know the trigger is really bad. Anyways put a good 10 - 14x scope on it and have fun.
