The factory trigger on the T1x’s give you a pretty good/usable range, but I put YoDave springs in wherever possible and adjust to about 60%
I’ve never fed a T1X any higher grade than SK Rifle match and even found great results with even lesser ammo working my way up to the SK level.
I might also suggest that how a 22LR subsonic round behaves @ 50m is different than it does @ 100. I’ve shot gophers with 22LR out 2.5X + that far, but do I think 22LR is a good or even 1/2 decent 100 yard option? No I do not.
So, to be printing decent groups @ 100 yards with 22LR…basically any error gets amplified. Let’s remember that a subsonic 22LR round is flying about 940fps @ the 300’ mark…and is basically shaped like a beer can. There can be no wind if you want good results…your technique has to be perfect and the ammo has to be the the gun’s top pick, and proven with tons of practice and super tight groups @ 50yards.
I would have no 22LR, 100Y tight group aspirations without consistently printing brag-worthy 50Y groups.
A coupe of unexpected T1x appetite preferences I’ve seen? Unfortunately for SK/AB gophers X you-don’t-wanna-know…CCI Velocitors are bought in case QTY. SK Flatnose was great for target shooting, no longer made? Inside of 50 yards plinking/pesting-never miss with CCI SV
Literally 2 guns rolling off the line one after the other can show different preferences. That’s how I treat it anyway. Buy/try lots of variety, leave Winchester/Remington branded ammo out and save some time
