F T/R Competition SFP scope for F-class

UndFrm said:

I was talking to a retailer and he told me that most, if not all, f class shooters use a SFP scope. I did verify that talking to some of the people. What the retailer couldn't explain was why, and I thought, I know where to ask.
I understand the difference between the 2, but I don't understand why SFP is better or preferred for F-class.

An FFP reticle would cover too much of the target to be useable across all magnification.

F class doesn't require the reticle to make corrections, so they don't care about the reticle measuring the same across all magnification. They use the rings on the target and/or dial in corrections.

This

And the fact that most fclass guys are old as balls and can’t see a FFP reticle zoomed out

Or, what if the center dot is small enough

If it were a very fine FFP crosshair or dot at 25X, it would be invisible or difficult to see against the black target face at 18X and below when we dial back due to the mirage moving heavily or boils....Cuz we're old and can't see.

Right

Would that stand true for any FFP, covering the target? Or, what if the center dot is small enough (not sure what moa)?

As mentioned above, if you made the reticle to be as small at its highest power as a SFP F Class reticle is.....you wouldn't be able to use it much lower than max power. Which would by default negate the reason to have any lower power. And if you negate that reason, you have no reason to make it a FFP reticle.

The Kahles 1050 for example is a popular F Class optic. At max power the center dot is something like 0.07moa. That would be just under 0.75" @ 1k yds. A pretty standard size for a FFP dot is 0.035 mil. Which would be about 1.25" @ 1k yds. That's about 40% larger. That also means that the Kahles covers 15% of the X ring, while the FFP 0.035 covers 25% of the X ring @ 1k yds.


So, it's circular reasoning. One thing leads to another, then another reason that FFP doesn't really work, nor is it needed.
