A very good friend of mine just got done doing a year of chemo and a stem cell transplant. Right before his treatment i took him to a 200 yard range and he had a blast. He asked if we could try out the 770yrd range and i am happy to do it. I have a 6.5 grendel with a leupold 3x9 that is pretty much automatic at hitting steel plates at 200 yards. My fear is that i will need more magnification to have a chance at hitting steel at 700 yards. I dont want to disappoint. This wont be for competition i just want to have a good chance for him to ring the steel at 700 yards. I was thinking something in the 14-16x range might work. I have done well with the nikons in the past and also the leupold. What would get the job done? Thanks for any info.
