Crosscheck chrono data

[AreWeFree]

I chronographed a few different factory loads today and am hoping some of you have data so I can validate if I'm getting accurate readings.

Please post any results you have, big thanks in advance!!

Crosscheck chrono data

The numbers look good to me. I have noticed on some of my box ammo for SD it will also show chrono avgeraged data from that batch. I will look to see if I have any boxes for pics. I usually don't save the boxes. Only the end flaps. I have seen in hard printed on the outside of the box, but have also seen it as a black ink stamp on the inside of the flap.

The only one that I would have thought to be faster was the 9mm Speer Gold Dots. At 124gr +P I thought they would break 1300 FPS. I know it is a short barreled G19. That could explain it.

You chrono data looks to be really close to factory data.

9mm Speer Lawman look good too.

I recently ran some factory 115 gr 9mm rounds through my chronograph and put this table together with the results-
