Went to my first national level match today with shooters across the US coming in to shoot at for NRL22X out to 400 yards. I was running my new Tract 4.5-30x56 dialing from 0 mils to 20.4 mils for the 400 yarder which I landed hits on. I also met up with the folks doing the MDT Steel Challenge who had a TT, ZCO, NF 7-35 so I didn't do side by side comparisons but I did get behind the glass. ZCO is great. They're so easy to get behind.
I don't think any higher end glass would've scored me any more hits today, so I'll stick with my glass until I learn to shoot better
The Ares BTR 4.5-27 which I also own, I would consider I outgrew that one. There were definitely many times the glass just wouldn't resolve with enough clarity on some targets on overcast grimy days. Grey steel, grey background, grey sky. But going up to the Ares ETR/Cronus, it holds its own against the Gen II Razor's and NF.
I'd say the jump to ZCO would be the only jump I'd consider.
