My 365xl with rds i pretty much have set at 25yards. The hipoint 995 carbine iron sights was at 50yards but now have a spitfire AR optic so far set at 33yards with a laser bore sighter. Still need to fire some rounds for final zero there and finally to 50yards. Remington 742 30-06 scoped is at 50yards and i think the ar15s are 50 also..been a while since i fired them though.
Only the operator..lolAnd all of those are air guns, eh?
