You more experienced guy's may be able to answer this off the top of your head. Just curious, How many mils of up adjustment would you gain by going from med. to low rings (which in my case is 1/4 inch difference) on a rifle zeroed at 100 yards?

Rifle Scopes Lowering scope 1/4 inch?

You may actually loose mils of adjustment by lowering. I was listening to a conversation a few months ago among some oldtimers who claim that raising a scope can gain adjustment for LR. If you start higher then you end up zeroing your scope several increments of adjustment below center. This in turn gives you more adjustment at distance. Sounded strange at first but after a while it became more clear. How much and if it's worth having a high scope? Don't know. I do know that on my two main LR rifles I can't go any lower due to objective diameter and they don't make any higher rings for my application. Can't test the theory so I'll leave that to those who can.
I believe you should be looking at a tapered scope base, most people using short action cartridges run. 20moa base.

I do have a 20 moa base on the rifle. I am just curious if I would gain adjustment by going to low rings. All that was available locally was Burris XTR 30 mm medium at the time I was putting things together. I do not want to lose up adjustment. right now I have 19.8 mils of up.
What caliber are you shooting and to what ranges (distances)? You may be worrying about something that will have no actual impact on your situation. Likely even.
For example, you can get to 1000 yards with a typical .308 load with 11-12 mils of elevation.
And to reiterate what's been said above, you will not gain anything by using lower rings.

Why don't you put the numbers through a ballistic calculator and adjust the value of the scope height over bore to see how much difference it makes for your application?
I tried it using some quick numbers on a .308 using same atmosphere and muzzle velocities... only change was the scope height over bore.
At a scope height over bore of 2.05" Ballistic AE called for 10.74 Mils of elevation at 1000 yards.
At a scope height over bore of 1.80" Ballistic AE called for 10.80 Mils of elevation at 1000 yards.
Dropping down 1/4" closer to the bore actually requires slightly more correction to get to the same distance. This seems to confirm Deadshot2's observations.

A 1/4" lower scope rings might just make that neck ache worse. Might I suggest that you raise your bipod a couple notches and use more rear bag? Check out Franks most recent tutorial on the home page where he discusses this very subject.

I would be more worried about a 168 amax going 2600 for 1k and beyond than lowering my scope .25" to "gain" elevation.
That should be about right with a 20-22" barrel. Going transonic around 1200 or so.
Why is your neck aching? This is an important point.
Is your cheekrest too low/high in relation to your scope?
You should be able to rest your cheek on your scope looking through it and relax most of the muscles without holding your head up or pushing down onto the cheekrest.
Shooting from prone? Are you too low in general?
I don't think the scope objective bell needs to be anywhere near the barrel if your cheekrest is set right. I use cleaning sponges and an Ace bandage for non-adjustable stocks and I can fine tune it well enough to get perfect cheekrest height within a few minutes. (you can stop laughing now)
I have a 9-13 Harris notched leg swivel bipod, a Triad tactical stock pack with all of the velcro in it. My scope height is 2.1. The stock is factory Remington 788. My rear bag is home made, old wool long johns with airsoft pellets for filler. The bag is six inches long. The tutorial that lash guided me to stated to try and get the rifle level. I normally shoot with the bipod extended one notch. Maybe I am trying to get too low. Like I said I have some experimenting to do.( you can laugh at the long johns rear bag)
That's higher than mine, most people go with a 6-9" bipod. I do and run it a couple clicks up so more like 7-8". To go 10" up I would require a small pillow under my chest to not be holding myself up.
What I would do is lay it out in the living room, close your eyes, lay how it's comfy, open your eyes and see if you're looking below or above the scope. My bet is on below resulting in you having to hold your high which can cause neck strain etc as well as not providing consistent mounting of the rifle.

The bipod height you choose can vary depending upon body size and shape, so some will find the 9-13" works okay for them. A person with a large belly/chest/body size will often be hard pressed to scrunch down and use a 6-9" bipod without neck pain.
Let the OP do his homework and see what the real issue is, since it is hard to accurately sideline quarterback a solution without knowing all of the pertinent details.

We're just offering suggestions. If he didn't want them, he wouldn't have posted this topic. Part of doing his homework is knowing what to study, we're just offering some tips. Trying a different height bipod isn't beating him on the head to buy an expensive item or to change something permanently.
