^^This thread suddenly turned productive, type of stuff I was hoping to see.

150 yards is not set in stone. I haven't spent much time thinking about it yet, and haven't done any work towards it. I'll learn as I go, and may learn not to do it. If nothing else, it will be fun getting a rifle set up for this purpose in the off season. My prediction is I get tired of waiting for a headshot, and put one through the ribs. I'll also only be doing this at my shooting range, which they frequent. I will be very familiar with the ranges, wind, lighting, and such.

Shaving 8+ms off the lock time would be useful, and I would like to keep the high velocity and affordability 5.56 ammo. Probably be cheaper to get a new 5.56 bolt action rifle than set up a .308 for it, and I now have an excuse to buy a new gun! Any recommendations? Taking Ar mags would be a plus. Ruger American is the first thing that comes to mind. I don't like that you can't lock the bolt closed on them, but I guess that won't be an issue when waltzing to my shooting range.
