"First, I am sure they offer a zero stop with 1/4 moa turrets. My two are not zero stops. One has a custom milled base that when sighted in is 3 moa off bottom. The other we used a 40 moa base and it is 10 moa or one turn off bottom. The zero stop is a great option, but not always necessary."
What's the diff between this and what I'm doing?
My intended use is to not crank it down to the stop then back it up to zero. The intention is to no have to remember which of those even numbered lines at the bottom are to be showing. I've been 10 MOA one time and 20 MOA another from looking at it wrong.
It is easy to see the turret knob approaching the clip ring. With 7 MOA to touch it, I should never go that far. Except by mistake of course.
Back in 1966 Cecil Dodge (Pocatello gun smith) was slow in getting the barrel fitted to my 270. He loaned me his personal rifle for the season. It was a Win 70 rechambered to 300 Wby. I was intrigued to notice it had no dials on the scope and no adjustments on the base. There was some kind of 6X or so scope on it. He gave me the hold overs. My doe was shot at 75 yds. While field dressing it my buddy shot a doe at 400+ yards. I asked Cecil if I could shoot jackrabbits with it. He said sure. I shot runnin' jacks till I ran out of those old Nosler partitions.
Loved that rifle. Cecil is one of the best men I've ever had anything to do with.
A study of the above video clearly, to me, shows that NF zero stop does not provide any upward force to the adjustment. Pretty nifty arrangement.
