Love the lack of recoil

I doubt you are getting any tumbling I've run the Berger stability calculator on it and at 600fps it has a stability factor of 2.47 any thing greater than 1.5 is stable, at 1050fps it is 2.98.[/QUOTE]

It may well have been a slight optical illusion caused by the angle of entry, as the shot was slightly down hill.
