Eley ammo mislabeled. .....

[Eagleye]

I have a case and a bit of a certain lot of ELEY black Match ammo
It is marked 1059 fps. I graphed it out of my SUHL 150 [avg 1042 fps]
My 40X [avg 1055 fps] Out of my M37 Remington [avg 1048 fps]
Out of my Mossberg 144 LSB [avg 1063 fps] Out of my 541T sporter [avg 1053 fps]
The overall average is 1052, so not far off the mark. This ammo is scary accurate in a couple of
my high end target 22 rimfires. D.

This is a good illustration that ammo will respond differently in different bores.
