[Getting a scope in SFP with that style of reticle is just wasting money if you're actually wanting to use the reticle. Most values are only true at maximum magnification on a SFP scope.
On a FFP scope,the values are true at every magnification./QUOTE]
You can't say "is just wasting money". Most people don't even understand the differences between FFP and SFP. Once you do understand, you can see that each has their benefit. FFP scopes magnify the reticle size as you zoom in. Some people find that a distraction, and don't like that feature. As far as the reticle spacing being true at every distance, that's easily off set by using a range finder, and/or learning that most scope of higher power aren't used at unknown distances on their highest power. If you have something like a 3-18 power scope the math is pretty easy to do even without a calculator. Set the scope at 9x and it's half, set it at 3x and it's tripled. I found that after having my first FFP scope that I preferred SFP. Some of my friends like FFP. You need to understand what it means and then decide.
The only reason that one would buy a scope that has a hold over/ranging type reticle would be to use it,or learn to use it.
It's kind of hard to use/learn them if you can only have the correct sub-tension values of the reticle at the maximum magnification of the scope when it's a SFP scope.
Yes,You can do the math and correctly calculate the reticle values on a SFP scope,but most have a hard time getting it correct,and it takes a lot of time. If your hunting,buy the time you do your math,the animal is gone or has moved.
Granted,on FFP scopes the reticle is pretty useless at lowest magnification,but once you get to 6-8x,you can see the reticle clearly enough to use it.
SFP scopes work great for hunting,or shooting known distances,but not so well if your wanting to actually use a ranging reticle.
Most of my hunting rifles have SFP scopes on them,All of my long range guns have FFP scope on them,because I use the reticles for hold over and ranging targets.
