I have a 7mm-08 that shoot well under MOA at 100yd. My load for it is 140gr Accubond at 2960 fps. I would like to think if I do my part with shot placement that I could push it out to 500yd if there was no option for a closer shot. I know there are better cartridges for 500yd shots on elk. I have owned several of the hard hitters in the past and killed elk with them. Longest shot on an elk was 360 so far. So what are your thoughts on this 7mm-08?
