60 mm will be my next upgrade.
Very interesting.
I had a 35mm IR Hunter MKII, and it was darn good. But, I"m just an average marksman and I need every advantage I can get. For that reason I upgraded to the 60mm MKIII and I truly like it!
My first IRD (Trijicon) was a mk2 35mm ... and for 2 years it met all my needs for "coop" defense ... then we ramped up the cattle production and I wanted ability to PID out much farther, so upgraded to 60mm which is a GREAT long distance spotter.
Last night, in the rain, I saw a "blob" in a spot ... and it was very hot, so I knew it was alive ... it had been raining for 3 days ... so conditions were "sea of grey". Our green house is on a rise and this blob could've been near the green house and closer, which would've meant it was NOT a cow. But it looked like the rear end of a cow (front end not visible). I inverted to white hot, but still no PID. I increased digital magnification to 8x (net 18x) ... and now I could see the tail swishing back and forth and could PID as cow. White tails, don't have tails ... and other critters have different tails. So turned out this was a cow at about 250yds. But the 60mm definitely helped with that PID. And I mount it on 5.56(10.3) carbine so it is easy to carry and hold up. I call it my "night spotter" .
... Tell me more about your 10.3 inch barrel please. What is the twist rate? What bullets does it seem to like? I've got a 10.3 inch Hanson barrel 1:8 twist that doesn't like 55 grain Hornady Vmax. It shoots 2-3 inch groups. I switched to my 16 inch Rock River 1:9, but I'd like to use my shorter barrel ...
