What would it come down to on full mag?
If it comes down below 10 yards then you really should adjust back up to 10 yards - the gaps will increase.
Reparallaxing requires removal of ring on end of scope then the part that is threaded to take the ring will turn. This is then adjusted until you are happy. Be aware that tightening the ring back on to lock it in place will adjust the parallax a small amount.
I never got on with round wheels on Nikkos - always used the Barry Taylor sharkfin type.
Gaps on mine are not huge but it snaps in and out so there is no doubt when it is in focus.
Be careful when adjusting the threaded part - the edges can be sharp.
