1 3/8" @ 100 yards. I ran a dampened windex patch down the bore this morning, loaded up and took it out in the rain/snow. Shoots in the fog was beautiful!
Rifle was covered with wetness from the mixed rain/snow and i wanted to test out the protection of the Flitz. After about 30 minutes inside the house the rifle was covered with a filmy white color where the rain drops settled down. I just used a dry towel and everything was like new again. Seems to do its job well.
