Had the 20 dialed in good. Went back to 30 and it’s 1” low. Using the lumix speedring scope. I noticed in the scope manual it says if shooting a fast crossbow experiment starting at 30. On this scope it has a triangle for the 20&30. Top for 20, bottom for 30. Shot several times to confirm it wasn’t me. Using a steady comfortable rest, squeezing the trigger slowly making sure I’m not jerking. I mean it’s a dead deer but I’d like to be better than that. Also only using one arrow. Thoughts? Thank you for any tips you might have. Shooting the KI Ripper 415 with carbon express mayhem arrow.
