Talley rings

[bigpete]

Is anyone familiar with Talley rings for the marlin 1895 ? Part no. 940336 ? I'm trying to work out what height I need to mount a leupold vx2 1.5-5x20mm on my Marlin 1895cb and I don't want to stuff the gunship around by ordering the wrong ones. All I know is that I'll want them as low as possible. Cheers Pete

I would have thought it was the gunshop's business to help you order the correct rings!?!

[bigpete]

Possibly. But if I don't get the right ones the first time then I gotta wait another 2 weeks for them to arrive

What's the diameter of the ocular bell on the scope?

The height of most rings is listed on manufacturer website. Ring height is generally given as measured from the base to top of the lower ring. You want the rings that are at least as high as half the ocular bell diameter (as this is the bigger bell on a 20mm objective scope).

Pretty sure that's right. I'm sure some one will correct me if its not. Also consider a natural view through the scope. You don't want to be too high or so low that you are straining to get into position.

[bigpete]

As I said its 20mm

[bigpete]

What I'm more worried about is if the hammer will snag the other end if I get too low

[bigpete]

Hence why I'm trying to find out if someone has run a similar set up

As I said its 20mm

That's the objective. Read my edit as the stupid phone posted before I finished.

[bigpete]

Hmm pays for me to read things properly lol

[Gwion]

Take a measurement from the ring base to the height of the hammer above that. Add the (half ocular bell diameter) and a couple of mm for clearance and that is your minimum ring height.

[bigpete]

Damn looks like I'll have to wait to get home

[Gwion]

They don't have the same rifle at the gunshop?

[bigpete]

Nope

[Gwion]

Nope

Try looking up the specs for the rifle online.

[Gwion]

Just looked up the Marlin web site and from the pics of the 1895CB, the hammer is lower than the body of the action. Allow a couple of mm (maybe 5mm) on top of the 0.5xocular bell diameter and you should have your minimum height.

[bigpete]

Cheers better try and find specs on the scope then or wait till I'm home and can measure it

[Gwion]

Ocular bell on that model is 1.6", 40.64mm.

[bigpete]

Just measured mine and I got 38mm. Halve that and I get 19mm which is a bit more than .700". Rings only come in .410,.510, and .610 inch. Am I missing something here ?

My boo boo: This is from the Talley website:

Where does Talley measure their rings from?
- On our lightweight rings, we measure from the top of the receiver to where the bottom of the scope will rest.
- Steel rings are measured from the top of the base where the ring sits to the bottom of the scope tube.
- Bases are measured from the top of the receiver to where the ring will sit.
- Our Picatinny rings are measured from the top of the rail to centerline of the scope.

[Gwion]

So, if i'm not completely mistaken, that should be your 19mm (make it 20mm) - 12.5mm (half diameter of scope tube will be bottom of tube: make it 12mm for the extra 1/2mm clearance) and you are left with 8mm as minimum ring height (0.314").

Any of those rings should be fine depending on your natural cheek weld. No point having it too high and looking at the bottom of the scope or too low and looking at the top of the scope. Ideally you want to be able to bring the rifle up, naturally place your cheek to the stock and be looking dead down the center of the scope.... ideally.

You could play around with the rifle and a ruler placed roughly where the ocular lens will be and see exactly where your eye looks when you "mount" the rifle. This will probably need about 18 sets of hands to do satisfactorily, though and is probably a bit OTT, but that's me. Subtract you 12.5mm from this number (center of lens=center of scope bell/tube) and choose the rings that are closest to that size.

[Gwion]

Another idea:

Fold a piece of card into an L so you can tape it to the receiver where the ocular lens would be (roughly), make on it the height of each tally ring plus 12.5mm. Raise and mount the rifle with your eyes closes and then open them. Which mark are you naturally looking at first. Repeat as many times as you feel necessary until you are confident which ring height you need.

Sorry... OCD kicking in. Been laid up with crook guts all day and a bit bored....

[bigpete]

Lol. Yeah I worked it out myself and have ordered the .410 height rings

[Tripod]

You want the Extra Low rings, plain and simple. Works perfect on a few of mine.

[bigpete]

Yeah that's what I ordered
