I am about to purchase a target riflescope for F-class competition.
Problem is, with this older action, I do not have the option of my first choice 30mm rings for a scope/1000 yard maximum range elevation capable.
I must therefore use, a one inch diameter scope and hoping not to need 20 minute bases.

The action will be in .308 winchester, probably using 155-175 grain weight bullets.
Is a Leupold VXIII, 6.5 X 20 LR target scope (one inch) have enough "come-ups" for these trajectories at up to 1000 yards/meters?

Thank you....:D
 
Why not go with a set of the Burris Zee Rings with the offset inserts. Cheaper than a 20MOA base and they achieve the same goal. I have them on my 6BR and can easily reach out to 1100m with them (furthest I have tried) and still had adjustment left, mind you mine is a 30mm tube too, so take that for what it's worth.

I doubt your Leupold has enough elevation in a 1" tube to reach out the distance you want to go with it without some "help" in the way of 20-30MOA base and/or Rings. I had a hard time getting my 7mm Rem Mag to 600m with a 1" tube scope and I still had to hold over a couple of feet on a 2' gong as I ran out of elevation and it was 0'd for 100 near the very bottom end of the adjustment.

i have a 308 and i had a bushnell 4200 series in a 1 inch tube and it was maxed out for clicks at 600m i them put a plus 20moa rail on it and it was fine out to 800m i have since changed scopes so i cant tell u if there is enough clicks to go further than 800m

Brutus, we can gear you up with a 20MOA+base and appropriate rings for the Wichita. Also have Nightforce scopes.

Even with a 30mm Scope you may still need more elevation depending on how far up you need to go to get your zero. 30mm scope and .020 ring inserts or 20MOA base is something you should still consider.
 
There should be an adapter to go from your dovetailed receiver groove to a weaver base. Worse case, one can be made. Check out Brownells/sinclair for many options. Look at the groove distance not necessarily for your make of action.

Once installed, you have access to any ring/scope set up you want.

As was previously said, the Burris ring system gives you enormous flexibility on scope and scope set up. My 223 uses an Elite 4200 6x24 w/mildots and I go from 100yds with 1000m using adjustment and reticle. I can get to 1200+m.

PS in general, a 308 is going to need 32 to 36min of elev change to go from 100yds to 1000yds. Most 1" scopes have enough travel ONCE it is shimmed. 30mm scopes should have more elevation but that is not always the case. Some brands with lots of internal elevation have optical and mechanical issues at the extremes of travel thus limiting their true range of adjustment.

Best case is to set up your scope for the range of distances you will be shooting for a match while the scope is in the middle of its adjustment range (best optics and mechanical stability). I doubt you will ever compete in an F class match that goes from 100yds to 1000yds in the same event.

That is why I like the rings so much. I can set for a 300m to 600m event or a 600 to 1000yd event without having to dial my scope to its extremes. Just move the shims to reset your zero.

Sounds like a major pain in the ass to me. If you just used a tapered base and an appropriate scope with enough internal elevation to begin with, you wouldn't have to contantly #### around with Mickey Mouse set ups.

K.I.S.S. anyone?
 
I don't about anybody else on here but from what I've seen, the Burris rings with the inserts are no longer made in 30mm, only 1" ?? So the problem is finding these and then trying to find the inserts (should you break one or need a different size, etc).

Also, I saw somebody mention that the new 30mm Burris tactical rings now have the inserts?

Any of this true?

If you care about optically centering your optics regardless of internal adjustment, then muck with them for the match. Odds are most matches you shoot will be in the same distance range anyways.

If not, then set up to use the scope elevation alone. Remember that some scopes don't work their best at the extremes of their adjustment range. Not much fun chasing a shifting POI at 1000yds....

Especially, when you don't know it's happening

YMMV as might your scores:runaway::D

heiko,
As to Burris reducing their Sig line up, WRONG. Check out the Burris website and you see that they have expanded this product line about 4 fold. These rings are selling great. They now offer the 30mm rings in three heights.

The 30mm rings have been upgraded a year or two ago so that each ring is now 4 bolts. Yes, the same set up as most 'tactical' rings and they are superb. Steel rings with very tough hardware. Maybe that is where you have heard about the 'tactical' rings now having inserts. These rings qualify as tactical.

As for their actual Xtreme tacky line up, NO PLASTIC HERE. But you get.....

6 bolts to clamp your poor defenseless scope. You better make sure that the rings line up dead on or you are in for some funcky action. Ironically, these are ALUMINUM.

Isn't marketing grand....

thanks Jerry...I never was a fan of the rather large looking Burris tactical rings. I'll check out the Burris site to have a look, great to hear the sig line of rings are still available in the 30mm with inserts.

Who sells these in Canada?

X2....Good information!

I would go so far as to say that most scopes degrade optically at extreme adjustments......Some Leupold scopes (with huge amounts of adjustment) offer the appearance of a dirty pop bottle at full crank....While they can get on target the view is far from ideal (not bashing Leupold).

The same scope can be a perfect choice with a 20 or 30 minute base.

Scopes with 1/8 minute clicks usually have about 1/2 the adjustment of a comparable 1/4" model.
