i am trying to decide on a scope. i have looked at the votex viper pst and the sightron SIII in the long range models. i like that in the sightron i can get higher power. the pst tops out at 24 power. does anyone have an experience with both of these or have experience on either one? i am thinking the 32 power for sightron or the 24 power for the vortex.
another question is in english dummy term what is the difference between front focal plane and secondary focal plane?
I got a Sightron SII Big Sky about a month ago, it blew me away. Before this scope, the nicest I had owned was a Nikon Buckmasters. The Sightron glass is crystal clear. It's 10x better than my Nikon. So far, I haven't found anything about the Sightron that I don't love. If you do get a Sightron, you may want to do it before they stop doing their $75 mail-in rebate. I don't have any experience with the Vortex, but I've heard very good things.
As far as first focal plane vs. second, with the first focal plane, the reticle will remain the same size regardless of what magnification it is set on. This is very convenient for reticles with "hold-over" marks (mildot, BDC, etc.). That way, once you know where your specific load will hit with each mark in your scope, you're all set. With second focal plane, the reticle size will change depending on the magnification level. This means that if you are shooting at 200 yards on maximum magnification and you are using the second dash in the reticle, once you reduce the magnification you will no longer be able to use the second dash down. The reticle will change size and you will need to recalculate to figure out what hold-over point to use. It's much less convenient to try to use unless you either: always use it on one magnification, or you use elevation adjustment to compensate for drop, rather than using hold-over points in the reticle. If you are planning on doing either of those, then it really doesn't matter whether you get first or second focal plane.
I hope that makes sense.

thanks for the reply's i have even gotten an e mail i think the scope i may be looking for is more to the sightron than the viper.

Either choice would be an excellent scope. The Sightron would be extremely nice for more general shooting / hunting. Whereas the PST might serve a more specific niche.
Here's a nice, and brief, explanation of first and second focal plane reticles. " A reticle located in the first focal plane grows or shrinks along with image size when the power is changed. This is common in the Eurpoean scopes. A reticle located in the second focal plane stays the same size as the power and image size changes. This is common in American scopes." Explanation from the "Exbal" program website.

Whoops... I got 'em backwards. My bad.Quote:

Very easy to do. I don't think it was too many years ago when we hardly saw FFP scopes on the market much....outside of Europe and perhaps the sniper world.Quote:

With a correctly made good scope, neither will affect POI with zoom.Quote:

Variable power scopes are just a fad that will soon pass.

I own both brands and both are very good scopes for their money.
LOL. So are smokeless powder and magnified optics in general.Quote:

I have two ( inexpensive ) SFP scopes that I had to put on .22 rifles because they had POI changes. I made my decision on getting the PST am glad I did.Quote:

Sightron Big Sky scopes deliver high quality and excellent glass at a reasonable price with excellent warranty. Whittaker Guns, Owensboro KY has the best selection of Sightron scopes and prices that I've been able to find anywhere. The adjustments are spot on with their Exact-Trac system. The SIII's get great reviews, but I've never owned one.
I've owned only one Vortex Viper scope, glass was very good, but not quite equal in my eyes to the Sightron Big Sky. IMO, Vortex is fairly new on the riflescope scene, but appear to be building a strong reputation. They are certainly bringing a lot of innovative features to the mid-price scope market that where once only available in high-end scopes.
IMO, both Sightron and Vortex offer top quality scopes, glass and warranty at an affordable price. To my eyes, the glass is superior to my Leupold VX-3's and they cost a lot less. Either Sightron or Vortex are an excellent choice. So it comes down to which scope, features and reticule you like the most.
I've never looked through a Sightron but recently upgraded from a Vortex Crossfire to the Viper 6.5X24X50 PA with the V-Plex reticle. The clarity, contrast and light transmission is excellent. Vortex's warranty and customer service is probably the best you will find anywhere.
im glad to hear that gacop, i have my vortex viper pst on backorder now hoping to see it by end of month cant wait to see it
The best deals i have found on Sightron scopes are at www.ammozone.comCan't say that everything is a better deal there but Sightron stuff sure is. it should show www.theammozone.comQuote:

You know if i would just copy and paste i might get this right.
Good pick, top of their line.Quote:

I've bought 2 of them from these guy's,they're great to do business with.
I can't peak for the Vortex but I have a Sightron SII36X42AO BRD (fixed magnification) on a 93R17 I shoot mostly from rest. The aiming dot is visually smaller than a .17 HMR bullet hole seen at 100 yards. The glass is as clear as can be, the Adjustable Objective near focus is 10 yards, the windage and elevation are in 1/8 MOA clicks, the guarantee is lifetime (regardless of owner, I believe), it holds zero flawlessly, and it came with a sunshade.

How much did the SII run you? I've been thinking about a fixed 36 power.
$379 a few years ago. It's now a discontinued model replaced by the SIIB3642BRD. click here for some sources of the discontinued version. The main difference between the versions is the full focus range on the SII3642BRD version requires two full turns of the objective and only one full turn on the SIIB3642BRD version. Other features and optical and material specs are the same. It's a very good scope for the money. The only other one I considered at the time—the only other one I could find—was made by Weaver.Quote:
