I tried the S&B ammo today and it shoots better than the Win NATO.
Course of fire was 5 rounds at 25 to verify zero, 10 rounds at 50, 10 rounds at 75 and another 10 rounds at 75 to end the trip for a total of 35 rounds. I would have moved it down to 100 yards but today was overcast and these sticky notes are not as bright as the pink ones I used on the first page so it all starts to blend in. I feel at 75 yards I could really start calling my shots since the target looked small with a harder focus on the front sight.
I think I did OK at 75 but it wasn't under the best conditions (I know, excuses). First being the guy on the left shooting a T/C Encore Pro Hunter XT muzzle loader accompanied with a cloud of smoke after each shot and two guys on the right shooting some ARs. The other was that I drank half a Monster on the way to the range.
I need to be more consistent with my holds to fix this vertical stringing. Either two shots went in the same hole or I had one really bad flyer.
First shot was on the right, outside of the note and I called the second shot that was right under it. I also saw the front sight dip on the two shots that's low on the cardboard.
Last grouping. I gave up after the first few pulled shots.
