Scope ring height

#1 Post by judders »

Hello all,

My new rifle is ready to collect now :shakeshout:and I've got a scope to see me through until I replenish my scope fund (epic MOT failure by the Landy wiped £1000 away :bad: ).

My question - is there an easy way of determining the correct scope ring height to buy, without having the rifle in my possession yet?

It's a Remy 700 with 20 MOA rail and the scope is a Leupold 10x40mm.

Cheers,

Jud

Brownells catalogue has a guide, as does the Sinclair one I believe

Want me to have a look?

From memory you'll need the Low rings for a 40mm scope

It is generally accepted that you want your objective bell (the end of the scope nearest the muzzle) as low to the barrel as possible without actually touching it. Not only does this help with adjustments and the amount of MOA you have to use between distances but it should causes less stress on your neck in achieving the correct eye position.

So assuming that you agree:

You need to subtract the size of your tube from the size of your objective bell
Then divide that figure in 2.
The figure you are left with is the hight that the tube needs to be off the action + a little.
Don't forget that your scope rail is probably a half inch or so high as well, you will need to measure yours as they are all a little different. Yo can subtract that no from the hight of the rings you need.
Most good manufacturers advertise the hight of their rings so you can purchase safe in the knowledge.

Clear as mud?

I think so.

So my calcs are: 40mm -30mm = 10mm / 2 = 5mm + 3mm (enough extra?) = 8mm.

Rail is already around 10mm. So backing up Saddler's comment about low rings being OK.

Or have I got that totally wrong? :?

On my Rem 700 I have a Leupold 20m0a rail, fitted with Burris 30mm high signature rings. The 'Scope' I have fitted is a 10x42 30mm tube. The objective lens is 6mm above the barrel. The scope rings are 7mm high and the front of the rail is 5mm high.
Your set up should work fine.

Doh! Maybe not then. :roll:

Typical, new toy and won't be able to use it straight away.

Oh well, good things come to those who wait....apparently.
