Went to the range and shot some 158gr PPU Defense line ammo at 50 yards. Got data on these shells with my Chronograph. I have not heard of the brand but it was the only ammo I could find 6 months ago. They were not grouping at all and the chronograph info states highest velocity 1779fps - lowest 1689fps over 21 shots. V for last shot at 20 yds was 1763fps and at 50 yds was 1542fps. I was using this ammo to get rifle toward center of target to establish drop of my reloads. However, my Chronograph gave me an error on each shot so it could not acquire information. Now that I am home I think perhaps the velocity was lower than what I had set the parameters to be. I selected rifle which range in one section says 1600 to 3900 fps and another 984 - 3900 fps. pistol is 400/600 - 1600 fps, so maybe I should change that since the recoil was noticeably less using the reloads. It could also be that I should have set up a second series for the reloads since they were so different. I will ask LabRadar what they think.
Anyway, the reloads did not drop and 3 grouped tightly with 2 to the left. They are numbered 5 on the right side of the target.

So I will load some more of the same and some with a bit more powder, talk to LabRadar and try again.
