What Size Scope Rings Do I Need For A 50mm Objective

Thread Status:: Not open for farther replies.

I have a 10 year erstwhile model 70 Winchester 7mm magazine long action of course with 26 " contoured barrel which is a great hunting rifle for the 100 to 300 k shots we go here.
I have gone from a Nikon BDC 3x9 40mm to a Leupold VX-R 3X9 50mmFireDot. The original
is smashing but will get on another rifle of mine soon enough. The reason for changing is not relevant
to the question.
The Leupold is a 30mm tube so original rings wont work of course.
I have e'er had trouble getting the correct set for 30mm tube scopes peculiarly the 50mm
throws me for a loop equally to how high the rings will raise the scope with weaver type mounts under
them.
Weaver fashion 1 piece with lots of options are a must for me. Or were till now.
Now I discover out Winchester model 70 long action total length weaver mounts are difficult to discover &
fifty-fifty get what y'all club! I ordered just that & it came in a curt activity which tells me they probably
didn't have whatever long activeness versions in the first place.
How exercise I know what the clearance will be with the 50mm & the barrel without it ending up way also
high or to close?
I take put scopes on all my life but 300mm stump me for some reason.
I have gone brain dead on this one.
I take all the Wheeler stuff for scopes.
But successful way I take ever been able to get the correct tiptop is to test mount in a cheap set of rings, preferably highs, so wait at how much I am too high or low, and find a good fix that gives me the peak I need. Noother method works for me considering until I get the scope examination mounted, I don't know how far forward or backing take to mount, and that can drastically alter the elevation needed on a tapered barrel.

Each ring makers high and medium IMO alter drastically! I was trying to setup a 44mm on a savage rifle and a 32mm on a single shot to clear the hammer and weaver medium were too low for the single shot to clear the hammer but burris z medium fit perfect. I tried burris medium on the savage rifle and it was a no get but leupold medium work fine. I'm talking like thousands of an inch clearance just each band did make a difference. Some may not concord with this simply this last time trying to find rings for my marlin and that single shot I just got a set up of medium and depression of burris and whatever didn't fit was returned. When I was setting up the two savage rifles I purchased medium, low, high burris and I could only utilize high so the others were returned but on the other rifle medium leupold worked go effigy.

Well if you have amazon prime or brownells edge memberships i would suggest ordering medium and high rings in the make y'all want, bank check them and send back which ever dosent work.
Brownells also lists this chart

And most ring and base of operations manufacturers list the actual heights of the rings and bases.
Ive been able to go abroad with medium rings on all the 50mm scopes ive owned also ones with adjustable objectives.

Information technology almost got it. And I really exercise cheers for your endeavour.
The trouble is I am not an adept on Winchesters, which is what I would accept to be to know which
model 70 I own! Mine just says model seventy on the barrel & knowing all I saw on the site, at that place are over
a dozen versions of the model 70.
I just know information technology is about x years one-time & the mounts the site told me would fit were not the ones at the
final page.
The height of the scope is 1 affair & another problem is the Leupold VX-R volition NOT FIT A Long Action rifle without a total length
mount or at least one side extended back over the commodities.
Just another half an inch within the scope would have made information technology fit both long & short action rifles.
And then much stuff these days is made to draw AR options, more than than one-half the stuff for firearms now is
for AR & similar rifles parts & accessories. I use them myself only -wow- it must be booming!
Looks like I'k going to accept to hunt & peck the same way yous do.
I just get something on my -to do- list & I need information technology out of the style, my health varies from calendar week to week
& I may non need this in my fashion.
Check out Warne mounts they are very good and might have something. Non sure if the link will assist but their base of operations finder shows just one long activity selection. When you say full length mount do you mean like a rail? I wouldn't imagine a 2 slice base of operations and that large of a telescopic having any issues mounting on a ii piece base just then over again I have no experience with the rifle your talking nearly.

Do you do online purchases such as amazon? If and then detect your base of operations and and then order a set of burris signature zee rings in medium and loftier and attempt them and if one doesn't fit then request a return with amazon and they e-mail y'all a characterization and you send it back no cost or at to the lowest degree I haven't had to. With 50mm obj I would imagine you would nee high rings as I wait at my 44mm on my savage in high rings its got about a pencil diameter gap nether the scope. I need high to clear the bolt.

Is your rifle push feed or controled?
I looked up the specs on your scope and its objective bell is virtually 1/10" smaller than the bong on my Argos 50mm. Id put money on information technology that youll be fine with a weaver/picatinny runway, and Warne medium rings.
Ill also endorse Warne rings, i similar em!
That existence said rings from any of the majors should be pretty good.

Ohihunters suggestions are excellent also! I havent used Warne bases, just the rings.

Echoing what LoonWulf said, mediums work the vast majority of the time with 50mm objectives. If y'all will call Warne and talk to their engineer Randy he can tell you lot which scope mounts you need. You lot can and then interpolate which mounts yous demand using other brands of scope mounts.

Leupold has a mountain finder on their web site.

Absolutely no reason to guess and no reason to waste time or money with junk stand-in rings...
All of the specs are online. You lot own the rifle, yous have the mounts. Lay a level across the mounts, either measure or eyeball an guess location for the objective bell, and measure the gap between the barrel and the level. Diameter of the objective/2 minus 15mm gives you the depth of the bell beneath the tube, subtract the gap summit measured above, that tells you lot the minimum height for the rings, below the tube. For brands which measure base of operations to centerline of the tube, add 15mm dorsum to that number.

Or....

Yous ain the scope and own the rifle, Cut an quondam deck of playing cards into skinny strips, half inch wide. Stack upwardly an fifty-fifty number of strips, set up them on the front and back of the mount rail, set the scope on top. Have out strips or add, until the telescopic has the clearance y'all desire. Once you lot have the superlative you want, measure the stack. That's your ring top. Once more, if the brand you're buying measures rings from base to center tube, add together back 15mm to your measured number.

Or...

In full general, a 50mm objective on a 30mm tube, on a commodities gun without an AR type handguard will use medium rings.
Your telescopic has approx ix.4 mm of bell located beneath the saddle or .four" for easy reference. I'd recommend something .55" or higher especially if you intend to use covers. Bolt clearance isn't generally a trouble with Leupolds. You'll need to of course account for the height of your runway. SWFA has numerous one-piece picatinney track in stock for long action 70s starting around $33. With runway, you're probably safe with .4" but most rings in medium heart around .5" Warne rings are a great proffer.

In the same situation, my arroyo was to telephone call Winchester and inquire. Their OEM rings are manufactured locally past Talley, and then I bought the non-OE-branded rings.
For something as mutual as a Win M70, any mounts manufacturer should know. Phone call and inquire.

That sounds valid I volition try it.
I got spoiled in the telescopic mounting deal because , years ago I bought all the stuff a gun shop had when they were going
out of business, for sad reasons. But none of the scope stuff is for 30mm tubes or long activity Winchester, now I run into why.
All the mounts & rings accept been a blessing thru the years, peculiarly for my sons & friends of course. Nosotros merely endeavour
various ones till they fit. Now nosotros are just about to run out of the easy stuff.
Thanks everyone, I've got it now, your advice has been priceless.
Thanks for all the info, it worked out nifty.
Stacked pennies & measured from mount to scope at working top then got the rings. Sort of a
version of Verminterror'due south instructions.
Used a total length Warne mount & medium Warne rings per LoonWulf'due south communication.
Would post pics but --- I --- take go just like a beau I used to criticize at piece of work for talking so much
during meetings. I would say : 20 people in this room & you are every other person that speaks!
I will listen hither instead of asking more questions. I tin can learn either mode.

Here is the result of our conversations:
Win Model lxx in 7mm Mag - 30mm tube - Leupold VX-R 3x9x50mm FireDot // Warne Mount -- Warne Rings
all done with Wheeler eq// Cheers everyone!!.
That's my method. I actually wish the ring manufactuers would adopt a standard and then you lot could merely option out the brand yous want and know it would work. I estimate they sell more than rings when y'all have to purchase something to run into if it fits and then something else because information technology doesn't. I relieve every set of rings I decide non to use just to attempt to cut down on this problem and expense.

The front end concluded up v/16" off the barrel, perfect!
I stacked pennies where the rings would get & fix the scope on them until it
cleared the barrel & mounts using all 5 of my hands. Then measured the stacks
in mm & inches then had to assume by the pics of the warne medium would
work & I did.
