Thoughts on FX No Limit Rings?

I am glad you asked! I want to know as well.

Overall - Decent price, easy to use, lots of adjustment.

Adjustments sturdy hold for a springer ?? 

They are a must at longer distances when your scope runs out of adjustment.

Dave, I couldn't answer that for sure. 

However, I do have a video on adjustable scope mounts. It's going through the final stages of editing right now. Should be up within the next week. 
It's a comparison between 3 different brands of adj scope mounts.

I got a set of these a week or so ago, LOVE them. Apparently more adjustment than the SportsMatch ones as well from what I've heard. 4mm adjustment equals 4m adjustment range at 100m, isn't the metric system badass?

Ted holdover has video on fx rings

Have no issue on my PCPs don't know about springer. But from what I have seen they are solid and high quality rings. 

I tried them on my aa tx200 .177 and wouldn’t recommend them on a springer. However on a pcp they are the cat’s meow!

I have them on my Impact and am happy with them,they are well made ,have plenty of adjustment , and have had no trouble with them holding adjustments ,at least under normal use.Maybe if they got dropped or hit hard enough they would move.

I’m a bit ignorant on anything springer but it my understanding that a springer is a rifle that’s best for shorter distances. I would then conclude that there should be enough elevation adjustment in your scope to properly site in your rifle. One other device that can give your standard rings more distance is a 20moa adapter rail which is a downhill from back to front rail that attaches to the existing rail.

here is one

here is a good explanation of what is 20moa for those of you who aren’t aware of this.

I have them on my 22 caliber Wildcat and 25 caliber impact absolute necessity 100 yards and out. Keep the Target in the middle of the site frame

Has anyone compared the No Limits rings with the Sun Optics adjustable and the Sports Match adjustable rings?

​I just picked up a set of the Sun Optics, and they seem OK, haven't had a chance to mount them yet. The Sun Optics are adjustable windage and elevation. Not sure how valuable the windage will be, as I bought them mostly for elevation to keep the scope as optically centered as possible.

I have No Limits on my WC .25

My thoughts:

-If you are buying new rings for new gun or scope, get these. Unless your mount height will be too much with these and you will not be doing long range.
-If you already have rings in use, buy these if you need to get insane amounts of MOA.

How far does one need to be shooting before these adjustable rings become necessary or preferable? 

Its totally dependent on the range of your scope elevation. When you run out of clicks and your still off target you need the rings to get the scope pointing lower to the horizon than the barrel. if your shooting lest than 100 yards you can probably shoot with out the need for them

I'd be zeroed between 45-50 yards and assumed I'd holdover beyond that, so probably unnecessary for me, right?

I have both and actually prefer the Sportmatch. Both are about the same except the Sportmatch have a micro adjustable set screw that allows precision adjustments (up and down)much easier. You can use the adjusting screw to raise or lower either ring and the scope stays put in between tweaks. With the FX you have to hold the scope in place with you hand and hope it doesn't shift while making adjustments. Not a big deal but a little easier.
