Thanks John, and much appreciate the others who joined in as well. I'll hang on to all that info.

Will start at 55, and work my way up a bit at a time. May not get all the way to 60.5, but I'm not greatly concerned about hitting the 2600 fps mark. Just looking to get minute of moose/deer/bear kill zone to a touch over 200 yds. Anything further than that goes free unless it's giving me an absolutely irresistable full side view!
