Home Forums Hunting & Shooting Long Range Hunting Scope question

In addition to holdover, there are a number of other valuable uses for reticle subtensions: spotting hits/misses and measuring needed correction, holding for wind drift, holding lead, measuring target size, estimating distance, etc.

Not all FFP reticles are faint at lower magnification, it really depends on the reticle design.

If the subtensions are accurate at 15x, then yes.

If the mag zoom range was 0x15 then 7.5 would be double.

The relationship between reticle subtension and magnification doesn’t depend on the range of magnification settings built into the scope. It could be a 1-15x SFP scope or 5-15x, the subtension values at 7.5x are double the values at 15x.

Yes and the relationship is linear not exp/log. so the starting point for the relationship uses the center of the range not the top range. This is how Burris Ballistic reticle relationship is set. As Swarovski does the same, at least in my Z6, by grouping bullet drops in 3 separate catagories, (little drop to lots of drop) then using their online program the scope can be set up for any caliber.

I'm not sure where you hunt elk, but no way I'd want an 8x or 10x as my lowest mag available. I hunt dark thick timber part of the time where 3x is the most I'd want.
If I were you, I'd shoot that rig as is, you might like that scope and you won't have to buy a rangefinder. You can always sell it later.
Otherwise, if you really think 500yds will be your max, any 3-9 with a ballistic reticle would work. If you can find the old 1" Vortex Razor 3-15 you might be able to get one for $500, great scopes. But even the $99 Burris FFII would work. I'm not a fan of FFP on hunting rifles, but many are.

Thank you very much. I believe I am just going to keep it as is for now. Get it sighted in at 100 and program the muzzle velocity and bullet coefficient and see how it does.

Good deal.
If that doesn't work, give the folks at Burris a shout-they will be helpful.

2012 was my first time to use a E-3. I am even shooting a rifle

Agreed that the relationship is linear, but the point of reference is whatever magnification setting for which the scope manufacturer calibrated the reticle subtensions. The Burris Ballistic Plex is typically calibrated for the max magnification setting.

The behaviour is easy to observe if you have an optical collimator, and there are even some phone apps that simulate it. Of course, actual shooting will verify the relationship, as I have done many times.

Yes Ive verified the relationship many times with many SFP scopes also. Have yet to find one that starts with mag at zero, could you provide a few examples. I want to take a look at them. Shoot 4 days week, long range, western desert Utah. You do you , I'll do me.

Jordan is right

Etoh is wrong

😁

It’s not always exactly half of the full power value where reticle subtensions double though

Determining this value is part of the Precision Scope Mount at Score High for second focal plane optics

Magnification adjustment marks on the scope aren't necessarily accurate, as such a test will reveal.

rcamuglia is right. No two scopes are made the same., and mag. marks certainly are not reflective of actual value. wasn't suggesting they were. my Benchrest NF has the hold overs set at 11x even though the scope is 22x, and my Hensholdt 6/24 is set at 12x both are SFP. Is that 11.5x or 10.5 and 11.5 or 12.5 on the Hens. , and thats to say nothing about no correction on windage. The only way to find out is to shoot it. (as rc suggests)

Never had the pleasure of shooting a manicured rifle range, fixed firing line, (on buckets list) most of the long range stuff I do has at least as much uphill and downhill error in the holdover reticle as the mag. guess. Getting old though, only shoot 20,000 to 30,000 rds. a year, not like early match days which was 100,000 for 3 gun IPSC, an occasional Steel Challenge, or hand gun silhouette thrown in.

If your curious about corrections for SFP, Sniperhides has excellent posts, a lot of "Barricade Benchrest" but not as much "tactical quarter groups" stuff as Campy

I never suggested that. I guess if you’re a fan of doing things the difficult, imprecise way you could shoot it and get close.

Not really difficult if you understand whats going on, and as you had someone do it for you I can safely assume that you don't. Their is nothing precise about shooting especially when the wind and inclination gets involved. Certainly nothing precise in the sense of 2 decimal places to the right. oh maybe the maching in the gun parts, and tolerance in bullets, but after that the random errors start cancellingl or negate all those those plans.

Oh and cut back on testosterone shots,, maybe add a little progesterone to off set it. And yes I have all the state and Federal lic. to say that. In 37 states as a fact.
