At first I thought $500 would be nowhere near a lifetime supply... but I see a deer about every 3 years and sighted my rifle in about 10 years ago. 3 sighters, 4 deer... that box is good for another 14 deer or 42years... not bad actually, unless I drop my rifle and need to re-zero. No rifle ranges near here or far that I know of. I'd like to shoot more but since moving down near Huntsville it's near impossible to "safely" have a session. By "safely" I mean without someone complaining about noise and/or getting red-flagged. Rangeview had some cheap fmj... g4c had some sp also good price
