Did some searching and found some decent info, but wanted to see if opinions may have changed since the XTR Pro has been out longer now.
I have a Cronus BTR 4.5-29 on one of my impact M3 PCP air rifles. It’s been on a few air rifles over several years now and hasn’t let me down. Glass is good, reticle is good, turrets track perfect athough they aren’t super “clicky” as mine is a Gen 1 BTR and not the Gen 2 BTR with the newest stainless turret detents.
I use this thing for occasional target practice in the backyard but mostly for taking out ground squirrels up to about 150Y. The 29x mag is very nice to be able to tell if that’s a dirt clod or a squirrel just starting to poke his eyes and ears up above the mound at 120Y+, and the glass in the Cronus is good enough to easily discern the eyes and ears from the dirt.
I recently picked up an XTR3i 3.3-18 for one of my 10/22s and really, really like it. I like the reticle, turrets are good feeling and track well, and glass is good, up there with the Cronus as far as I can tell, far better than I expected given my previous very poor experience with a pair of Steiner 3-15 T5XI’s. Using the XTR3i got me to thinking about maybe trying an XTR Pro 5.5-30 to replace the Cronus, even though I really don’t have any complaints about the Cronus other than the turrets could be a little more tactile.
How does the XTR Pro glass stack up against the Cronus BTR? Also, how’s the depth of field on the XTR Pro at 30x? One thing I like about the Cronus is on 29X I can use the parallax knob as a fairly accurate rangefinder at 150Y and in, which is very important on the air rifle given the trajectory of a pellet or slug. Sometimes in a very flat field I can’t get a good range with a laser rangefinder and instead use the parallax knob at 29x mag to range the squirrels, and the Cronus does pretty well in this regard and usually rewards me with first round hits. I know most people here are looking for just the opposite, a more forgiving depth of field so you don’t have to mess with the parallax as much when engaging targets at different ranges-- but I’m hoping at 30x at 150Y and in the depth of field is tight enough that the XTR Pro will let me get a good approximate range with the parallax knob.
Also, does the XTR Pro exhibit any noticeable image degradation when dialed near elevation extremes? I have a decent amount of cant in the mount for taking long shots, but since the Cronus does start to lose some image resolution when dialed within about 7 mils of the upper or lower elevation extremes I chose a mount to keep the Cronus above that area of degraded image resolution at my zero distance. However, since the XTR Pro has less elevation travel than the Cronus (26 mil vs 32 mil) with the current mount the XTR Pro is going to be dialed down to about 4 mils up from the very bottom of its elevation travel at my zero distance. Any issues with degraded image quality of the XTR Pro when the elevation turret is cranked down that low?
Thanks!
