Hi Lance, thanks for the info, I'll likely hold 400 or so as max range for 105-107s, but based on the damage with the amax at that distance on my deer, I'd imagine it would work further out, but how much I don't know. I don't routinely shoot that far, usually under 200, but want to know what my limits are should the occasional long shot present. I do know there is one set up I have hunted/may hunt again-where shots Can be at 600-650, cannot remember how far it LRF, but I'd have to have a perfect hold/rest and know the exact drop to try a shot that far, and in that stand I am not sure I'd try it do to lack of getting a rock solid rest on that shot.
Thanks for the info. BTW, I'd guess in your rifle, on those 500+ yd shots, the amax being softer/plastic tipped, may offer you better expansion at lower speeds, but would not want to use them under 200-300 unless you realize they will vaporize and a neck spine or possibly a lung shot would be almost a necessity. Looks like what you have been using works well and I may try some SMK myself, thanks.
