This type of scope really is what I'm after for a handful of rifles. All hunting guns. I've spent a ton of time behind almost every 3-15, 4-16, 3-20, 4-20, 5-20 scope in the alpha class. I've owned 4 zcos, Many tangents: Both M and P models. Too many Schmidt to count.. You name it, I've bought it. Multiple times. Ask
@CSTactical lol. Some of that is from not being able to afford 10 scopes in front of me at the same time to do direct comparison.
The ZCO 4-20 is a fantastic scope. It really is. Few things aren't my favorite but hey, personal opinions. Weight is one. I would prefer a sub 28oz scope. I would prefer a thicker reticle for when it's on 4x. Just a gen2Mildot would work well. Or the P4F (the thickness of the one from the 5-20us at .07. Not the one from others with the .04 center) It makes a difference from what I can see. The minox Zp5 3-15 with MR2 comes to mind for a good reticle too. MR5 is also useful. If the reticle is not big enough to be useful on 2,3,4x then like others said, it better be bright. Otherwise what's the point of even having it on 3-4x. Especially for me if hunting in timber.
I second the guys saying no need for more then two rev turret on a hunting gun. At 10 mil / rev, who is actually dialing 20 mils regularly while hunting. I would never get out of the first rev. Capped wind is fine. One thing I've noticed is on hunting guns pending where the windage turret is located on the ejection port I will get brass to hammer the turret and go right back into the action. My Lone peaks did this even with 1.1 rings. My Defiance actions eject right at 3 o clock so they still clear the biggest of turrets (TT professional) and not an issue. Just things that I have to make sure are right when I'm counting on it in the woods. Yea, you can mount the scope higher, then you need adjustable comb or a bag rider adding even more weight. But I'm no way putting 1.5 rings on a hunting gun.
I dont use a clip-on yet but
@SkyScrapin brings up points that may be useful on the lower end. However, if the FOV is wider at your 3/4x then say another optic at 2/3x, then what do you really gain by possibility compromising other items going to that 8x or 10x ratio? I'm no expert here. Without looking at numbers for FOV, if the NF at 2x is the same as say the Schmidt at 3x... how does this relate to FOV through a clipon..?
@Glassaholic and I spend a lot of time looking through these scopes and personally this discussion pushes the buttons for me on my most needed scope. We both have needs for higher end mil/mil scopes with 3-20 ish mag ranges but usually the kicker is reticles and weight. Right now the TT315M with mildot reticle checks the most boxes. Followed by the 3-20US with the new dt2+ turrets.
I would be all over a lighter weight 3/4-18/20 ZCO with a more simple thicker hunting reticle. Make the tube 30-34 if it's needed, and something in the 6-10 mil per rev turrets. Cap the wind if you have to. Well I'm in. I'll take two.
Excuse the typos, I'm on the road.
