Elevation wasted for zero @ 50m

[KWhorenet]

Was going to contaminate someone else's topic with my scope fitment issue but thought some others may benefit if I get this process sorted.

Just fitted a new scope to my new Savage BTV 22lr.
Gear:
- Leupold Mark AR Mod-1 3-9x40 FireDot-G TMR
- Leupold PRW low rings
- Stock weaver style bases

Problem started with first sighter about 1.5ft low at 50m... To verify scope was actually set to zero at 0 dial positions from factory;
- I ran dials all the way then back again to count clicks, then back half way for both. Both zeroes were spot on (half total clicks = dial position 0).
- Visually re-checked mounting. All looks good.

*Still shot 1.5ft low.
- Aimed at low shot, wound up elevation a whole turn till reticle was just above original point of aim (target center). Sorted.

Main question:
- Has anyone had success finding lost scope adjustment by switching around bases or rings from front to back or rotating 180 deg one at a time in case there is tolerance to play with ?

- I will digital calliper measure each part in case I can solve/improve it that way first.
- I have no concern using 'shim stock' to go under the rear weaver base but would like to avoid that if possible.

If I'm missing something simple or there are any suggestions for working with what I have it would be appreciated.

Cheers,

K

I'm failing to see what the problem is....setting the scope mid reticule is no guarantee it's zeroed for any rifle at 50m, that's part of why they have an elevation adjustment. What's the ballistics say about drop for the cartridge your shooting? how much elevation adjustment is left when zeroed at 50m? What's the MOA per click? Assuming you started mid reticule you have already wasted all the windage below that point anyway. I run adjustable rings so I can zero my rifles at 100 with only 5-10 clicks from the bottom stopper which in the NXS 8-32x56 leaves me around 60MOA of elevation to play with but I'm shooting out to 2000+ meters. If you have a turn or 2 of elevation remaining when zeroed at 50m then that'll be plenty cause the round isn't particularly useful much past 100m anyway. Did you happen to mount it sideways? It happens...

I agree with your points Brett. It is only a 22lr.
It's a 0.1 Mil/Mil scope. Theoretically 10cm at 100m per Mil or ten clicks.
Will see how much elevation is left in it. If I have 3 Mil worth left to play with I shouldn't be concerned as you point out.

Ideally you want your scope near the bottom end of elevation adjustment at the closest range you want to zero.

For a .22 that may be 50, that will allow you to click up to 100m, perhaps even more. I've had my scope on my .22 maxed out and using hold over shooting steel plates at 350m

Just click down to your 50 m zero and go shoot it, it's a non issue in my opinion

Chronos,
your example of plinking out farther is reason enough for me to attempt to change it. Shooting paper out to 100m bores me. Lobbing to a old saucepan is appealing.

Will measure the bits, get the most out of that then look at other options to enable near bottom for zero at 50m leaving most of the elevation available.

Thanks guys.

Wouldn't be the topic by that idiot who put his new Leupold on 90 degrees the wrong way would it?

You mean you Lorgar

Yes, that's the idiot I mean

As you wish.
