I put on a 12x lyman on my old 37 and boresighted it.i was aiming at the #5 you see and shot these 5 with Eley black box Match.i thought the group was about inch (but close to POI ) so I put the gun back in the case for next week to find tune.when I grabbed the target I was floored. I was seeing light from other holes through the target backer! I'll take it!!
