Decided to get the bushnell elite tactical lrhs. I'm having a tough time deciding which one to get. The 3-12 or 4.5-18. It's going on a 6.5 creedmoor at first. I'm trying to get set up for hunting. I'm a newby. This scope could potentially go on a ar15 in 6.5 grendel also. If I like it well enough I might get another that way they both have one and I don't have to switch. Any thoughts or recommendations? I'm leaning towards the 4.5-18 because I just don't see me really losing much with it compared to the 3 lower power, but gaining that extra on the top end power.
