I’ve killed a pile of animals with 200gr subsonic makers. Including deer, big hogs, and a cow I processed. Anyone that says subsonic ammo is not ethical has clearly never shot makers. Paul (the owner) is a great guy to deal with as well.
I would be carful trying to push that light of a bullet at subsonic speeds with that much case capacity. 300 blackout is another story. 4 grains of trailboss and a 125 out of a 300 blackout is pretty sweet.
From what I understand the reticle moves on the screen when you sight it in so the adjustments are not relevant to your poi when used in clip on mode with a day optic.
I am currently going back and forth with L3 trying to correct a pretty substantial shift with my LWTS. Tech asked me in an email if i have bore sighted it. I know some clip ons you can adjust the screen for impact shifts, but if you can with a lWTS I can’t figure it out. Image is pretty good...
