"Competing in LR F class, there is pretty much 3 brands you find on the line - Sightron, NF, and March. A few use S&B's. On a rare occasion, you find other brands like Leupold.
The optical difference between Sightron, NF and March at 1000yds isn't as great as their price suggests. In fact, it is very small. The March is certainly better but not by much.
From my personal experience rating them optically at the same mag ie 40X - MARCH, NF BR and Comp, Sightron SIII, NF NXS
I have not included the S&B 50X scope as I have spent very little time behind it and I didn't play around with the focus. Owners settings could have been different then mine so not conclusive

I posted this in another thread down this page.
You have already heard similar thoughts from other F class competitors. I know all about the "get what you pay for" adage and have stayed to this with my optics for most of my shooting career.
Search for thoughts and comments from other shooters around the world. Look at pics of events at F class matches. You will see what I have said above.
Buy what you can afford and what you BELIEVE in. That goes a long ways to having confidence that you made the right choice. Then test the scope and if it holds up to your needs, enjoy it.
The 'too good to be true' adage runs deep and most time, it is correct.
I compete with Sightron scopes cause it works BETTER for me then NF and MARCH. Cost is not the issue. Now, if a new family of scopes comes out that offers me BETTER, I would be a fool not to consider and I would.
Personally, I use a Custom Shop SIII10-50X60 on my FTR rifles - LRMOA reticle in a 1/8 min chassis. Love it and it does what I need for F class. I leave it at 35X and rarely change it regardless of the mirage levels.... and I have shot in real soupy air. For me, I want to see the mirage and the amount of mirage also tells me something. I will turn it up if air allows but rarely go over 40X - just too much chance to cross fire
Many shooters use and love the SIII 8-32. It works too. I just prefer more mag. It isn't a huge difference but I like the 10-50 better.
Ultimately, you have to get behind the rifle, look at the target under a range of conditions and decide for yourself.
The best way to do this is get out to your PRA intro days. Assuming you are near Homestead, get out there and meet some superb and highly talented shooters. You are going to see product from all the known brands. EVERY shooter has solid reasons why they chose that item.
Get behind them and see what works for you. As long as you are dealing with a known quality product, choose the one that fits YOU!!!
