I have 3 Lone Eagles. 22-250, 7br and 308. The 308 is the only one with a muzzle break on it. The break is one of the early Magnum Research cannon types. The center grip on the Lone Eagle makes the gun recoil up rather than straight back, what I am trying to say is my Ruger in 454 recouls harder... it is harder on the elbows and shoulder than my 308.
I don't shoot my 308 much but did at one time preparing for an antelope hunt. At that time I was getting sub 2" groups at 200 yards.
The trigger on the Lone Eagle is not light and has plenty of creep but with practice can be mastered.
All in all the Lone Eagle is a great hand gun. If I had my choice between 2 of the same Lone Eagles, one with a break the other without in 308 I would get the one with the break. I would not get a break on smaller calibers, I do not own a rifle with a break.
