Does someone know which one is more expensive to produce ?

Given the prices of them I'd place a fair bit of assumption on FFP

I don't know that either is more expensive to produce than the other, as each have their own issues.
A FFP reticle needs to be smaller due to its location in the optic, theoretically making the reticle itself more difficult to produce.
According to S&B, it's more difficult to make a SFP scope not shift POI during power change. In a FFP scope, the target image and the reticle are on the same focal plane and are magnified simultaneously. So, even if the center of the reticle isn't exactly on the centerline of the image, it doesn't really matter as long as it doesn't move. In a SFP reticle, it does matter if it's not perfectly centered in the target image because as you increase magnification, the amount of deviation error increases proportionally, causing a POI shift. Also, a SFP reticle element is located inside the zoom tube and can therefore move slightly when the power ring is rotated if the design isn't sound and mating parts are not held to very tight tolerances.
I don't know how much or even if those considerations have an influence on manufacturing costs, though. Edited by RifleDude - January/26/2011 at 12:08 |

I see. That can be a very fast and handy way to range things. Much like the Leupold 16" duplex numbers they'd put on the power dial on Vari-X III's for quickly ranging deer. That can work very well and I can see how you'd like to stick to that method when you know the size of the targets beforehand and especially if they're all the same size. If they didn't tell you how big the targets were until it was time to shoot, and/or the targets were different sizes, I think you'd find ranging the conventional way your best option.

I thought a good sfp scope would cost more to produce because of the change of impact due to magnification change. Also I wouldn't doubt for a second that a company would jump at the opportunity to increase profit margins based on customer desire. Just because something cost less to produce doesn't mean it's going to cost the consumer less. |

I am in the market for a new scope for my new Remington 700 LSS .257 weatherby magnum for 80% hunting and 20% target shooting.
I grew up with and always used scopes with SFP. With all of the talk about FFP reticles I ordered and just got a Vortex Viper PST 4-16x50 FFP. I also got it for really good price (only $50 more than the SFP).
As I have said, I have always had SFP and this FFP is quite different with the reticle changing in size with the magnification. Before I put this on my rifle should I send it back and get the SFP (which I am familiar with) or give the FFP a chance because it would be better for my set-up and use i the long run? TIA |

You have to remember, the reticle isn't really changing size. It will always be correct, no matter what the zoom setting. If you don't like it or can't get used to it, send it back... But that is all on you, it's your dime!

If it is tourist season, why can't we shoot them?
