Re: closest BSA mil mil scope to a u.s..optics?
To the OP, the UN-asked Genius Question:
For what purpose(s) on your .22 trainer?
If to merely dial the same mil-clicks to chase bullet impacts/wind and elevation zeros, then just about any of the choices listed will do.
If to as closely as possible duplicate the shooter's *operation* of the scope, then continue to question, and all useful replies above need to be updated. Same reticle? Direction of "UP" on the dial? Direction of "Right" on the windage knob? Location and direction of the SF knob? Direction of turn of the power ring? Anything else like an illumination function?
Don't rag on the OP for not having the discretionary coin to put the exact same spendy optic on both rifles. Valid, iffy or stupid, he has his reasons for his priorities this year. We work with what we have, don't like it then lump it and return to the helpful ethos of the Gunny Community.
My personal experiences with the WOTAC SFP 2nd-gen was not good. One came unscrewed at both ends, and the replacement lost any elevation 12 clicks from the bottom and its reticle rotated about 20 degrees. Until the batch that had 7-8 with that problem, their return rate had been 1%. The 4th gens and up are better and more durable. I now have an FFP model. It's going strong.
In between, I got more than a year out of the Falcon Menace...but...Took that mainly b/c I was sick of waiting for a replacement, and to try the FFP variation.
I can tell you first-hand that the Falcon Menace FFP 4-14xsmallerobjective has a GREAT reticle, far better IMO than the traditional 5 mils down from the crosshair obsolete approach. But my little old M1A killed it with probably less than 1,000 rounds. And I'm not falling down hills or butt-stroking hostiles with mine, either. Reticle subtension and tracking were perfectly accurate to either perfect or maybe not more than .05 mil (half a click) over a 10-mil span, checked both optically and by shooting. But the sidefocus started drifting to where I had to put it on infinity to see clearly at 200, then it drifted drastically some more to where I had to CRANK the ocular and suffer horrible parallax to get a clear image. Matt Wonders' attempts at customer service were perfectly honorable but wait times between shipments were approaching two months and I wanted to shoot. Bottom line for me: Falcons are probably nice for .22s but I won't put one on a .308. Unlike the WOTAC line, I just have not heard of any attempts to improve the Falcon product. Wonders is at Falcon's mercy there, and I believe they have come close to screwing him over with the occasional bad and not-durable product.
Wonders, on the other hand, is always tweaking his products in his WOTAC line, and has been aggressively testing the latest models with some severe recoil simulations. His glass is now a bit better than Falcon's too.
So, look to your purpose and buy accordingly. I hope that for you, you never have to use anyone's excellent customer service...
