anyone shoot 6br or any 6mm in encore. how do they do on deer ? i think a 80gr. sierra single shot bullet should do the job.

I have a 6mm Bower Hustler, 6x444,That is becoming a real tack driver. Last week I put 3 into 1" at 300 yards. My favorite right now is the 6.5 x 284 Van Horn barrel. At 17 inches it is a real sweetheart to carry and shoot. I haven't found the perfect load yet but I am working on it
