Scope FFP (First Focal Plane) Necessary?

Exactly. It makes no sense when you are in the game of long range precision to not have turrets that match the reticle and a FFP scope with a decent reticle pattern. You have tons of options for engaging targets and eliminate the constant errors associated with mil to MOA conversion. I can never understand how on earth you would want a mildot reticle that is not in the first focal plane. I use hold overs constantly and depending on the type of shooting, i may rapidly dial in the correction. No math required. It is too easy to do.
This is the key thing. Simple reticles only really allow you to do elevation or leads/wind hold-off separately. They do not allow you to take full advantage of FFP.
Reticles like these do:
And Horus, of course!
They allow you to do combinations of: holdover + wind, holdover + lead, or holdover + wind + lead more effectively. These reticles were designed for this purpose and you will be hard pressed to find them in an SPF scope. Having a reticle like this that is only true at one magnification is going to burn you every time it isn't at the magic magnification, and that magnification may not give you the right field of view in every situation.
This has turned into a useful thread...
I assume a good knowledge of bullet drop (in mils) is required so one would need to stick with a certain load unless they want to go through everything again
Is there a way/chart/list of common calibres-loads and their drop in mills at various ranges so one could avoid needing a 1000m range to 'discover' the bullet drop?

It does require you to know your dope, and yes, using a common load simplifies that a lot.
JBM with Litz models and good velocity data is very accurate. I run Ballistic FTE on my iPhone (which uses the same models and engine) and I'm never more than a click or two off. Just make sure that things like environmental conditions, distance to the chrono and scope height over the bore are also accurate. Garbage in will give you garbage out.

That works ok at closer distances, but the further out there you get, the larger the error becomes. I agree that some of them are way too busy. I find that is the case with the Horus ones. But ones like the three above aren't bad at all.

I gotta admit, I love the Vortex reticle the most. Too bad they don't offer it in the PST line.
Is it just me, or does S&B not offer a christmas tree retice?

Here's a decent rebutle to those who favor SFP:

He also mentions moving targets.

I wouldn't question my reading comprehension. Your verbosity doesn't make you intelligent. You still haven't given any examples of how FFP is beneficial outside of ranging/milling. The reticle has nothing to do with FFP. You can get horus style reticles in non-FFP scopes and they function the same as in FFP scopes. At the lowest power a "busy" reticle would likely be illegible using an FFP scope.
Thanks for coming out though.
Maybe you should actually try shooting with one... get some real life experience. Preferably under the guidance of someone who knows how to use one. Perhaps they can also explain to you the difference between estimating distance and compensating for trajectory.
Then come back and we can talk about who gets the participation ribbon.
I agree with you, the advantage to FFP is that you can range and mil at any magnification. Regardless of FFP or SFP the reticle assists in milling and the task can be accomplished using either. Theoretically it is easier using FFP because you can do it at any magnification.
You keep chasing your tail. I don't need to physically pull a trigger to understand the function of the scope. Tell me where I am wrong:
1) An SFP scope can range
2) An FFP scope can range
3) An SFP scope can hold over
4) An FFP scope can hold over
5) You can mil (compensate for elevation or windange) using any milling reticle (mil dot, horus, NPR-1, NPR-2, etc)
6) You can mil using SFP scopes
7) You can mil using FFP scopes
8) An SFP scope has a the ability to range and mil at any magnification, but is accurate at a specific power and requires an adjustment calcuation at all other powers.
9) An FFP scope has the ability to range and mil at any magnification and is accurate throughout the magnification range requiring no calculation.
Exactly, It's a very simple concept!
The only reason I said theoretically is because not everybody is the same.
I am not against FFP scopes and understand the feature. I just personally don't like how the size of the reticle changes. It may just be something I would have to get used to.
