Re: For those of you with FFP...

Pointman, they just don't get it. It really frustrates the hell out of me. There is so much disinformation about FFP vs SFP that it just drives me crazy. You said it first Pointman, holdovers are done exactly the same on both scopes. As someone mentioned, as long as you don't change magnification between shots. Even if you do change magnification, you simply measure the difference between POA & POI on the new setting, and hold over that amount. Follow up shots are done at exactly the same speed in exactly the same way with both types of reticles. I don't know of anyone who changes magnification in between initial shot and follow ups.
I've stated before, and been flamed for it, that ranging a small target at long distance can not be done near as accurately as a rangefinder. A garage door? Absolutely. A small target of about 5" by 8", no way. If you use reading glasses, good luck. I want my shot to be as precise as possible. A rangefinder trumps an FFP scope every time.
FFP does have some strengths. For targets of known sizes, and varying distances, FFP is great for ranging, as long as the target is of adequate size. For a small target at a long range, say 800 meters +, you would have to be at max magnification to get any kind of a decent measurement. With mirage, you would have to drop down in magnification. The target gets smaller, the reticle gets smaller, the subtensions get closer together, and it gets pretty impossible to see if your reading is .6 mil or .8 mil. If you want to hit the target in as few of shots as possible, hopefully 1-2 shots, you need the precision of a rangefinder, not an FFP reticle. FFP is tactical. Great for a semi-auto or doable with a 10 round detachable mag bolt gun for ranges under 800 meters.
The only advantage of FFP is subtensions remain the same value at any magnification. If you need to <span style="font-weight: bold">dial dope between shots,</span> you don't have to worry what magnification you are on. 1 mil = 1 mil. 1 MOA = 1 MOA. For hold overs,<span style="font-weight: bold"> it doesn't matter if you have SFP or FFP.</span>
For dialing dope, SFP is 1 mil or 1 MOA at max magnification. Backing off 1 magnification is usually enough to get rid of mirage. Here is the complicated math on my scope.
24x 1 mil or 1 MOA
12x 1 mil or 1 MOA x 2
8x 1 mil or 1 MOA x 3
6x 1 mil or 1 MOA x 4
It's not that difficult. If you want to adjust for mirage, find the proper magnification and use the large multiplier of 1-4. I doubt you will need to hop back and forth between magnifications.
For targets 0 to 200 meters, use iron sights, red dot, or low magnification.
For targets 200 meters to 1800 meters, use SFP or FFP, makes no difference.
Use a rangefinder and if the batteries die, range with the FFP with shrinking subtensions, or SFP with complicated math like 2 mils x 4.
