Ring height vs point of impact

[TommyD11730]

Hey guys
I have always used the lowest rings I could get my hands on. To me it was the most comfortable way to shoot off a bench.
Well I'm (getting) older now. Have some issues with the cervical spine, blah blah blah. So I just replaced a set of .961" rings with some 1.261". Figure ill give it a go and see if it gives me some relief.
My question is anyone's guess how much lower my POI @ 100Y my next trip out will be?

Thank guys!

Simple math tells me .3". -- Barring any other factors. jd

Assumptions: you’re remounting the same scope on the same rifle without making any adjustments to the scope, and that the scope was/is trued/plumbed to the bore, and that it was previously zeroed at 100 yds, the maximum POI deviation should be the difference between the ring heights. If the assumptions are correct, all you’ve done is raise the line of sight 0.3 inches. As that line of sight and bullet trajectory previously intersected at 100 yds (100 yd zero) your trajectory will be a fraction of an inch below the sight line at that range now.

I’m not certain but I will try to help. Assuming three things, scope was zeroed at 100 yds before, that your scope and rings sit exactly as before, and you don’t adjust the scope, your point of impact will shift down by the difference in ring height. My reasoning is this. Instead of visualizing that the rifle is the same you are raising the scope, think of it as the scope is not moving and you are lowering the rifle.

Should be plenty close enough to be on paper to rezero as others have said.

Youl be fine..and a bit more comfortable hopefully.

Talk about overthinking it. Thanks guys!

Tommy -

Howdy !

You can run your numbers through something like Hornady's
on-line ballistics calculator. The inputs you make include specifying scope centerline mounted height above bore centerline. You can then compare the projected bullet trajectory changes that result from the scope mount height changes.
