New to thermals here got them to hunt hogs so I got a TS35-384 on a 223 with a silencer have it sighted in about 80 yards when I sight it in on the range it’s dead on and then when I take it out I’m off usually over so any ideas or what yall think I should do and I also have the clip on the tc19 and I’m wondering what’s the best size of scope to run on that
