Have not heard anything good about Federal RF ammo in a couple years.

 

I have three CZ455 rifles:
Training Rifle 24.9" with 5/32" J&P aperture
UltraLux 28.66" with 1/8" J&P aperture
Varmint 20.9" with Nikon Buckmasters 6~18x40 AO

I have tested three lots of Federal Premium Match 711B (boxes of 50) produced from 2013~2017 through each rifle and my Shooting Chrony Beta with the following results:

Here are my results for CCI Standard Velocity / Green Tag from the same period:

Abbreviations:
Tfps = Training Rifle muzzle velocity (fps) through my Shooting Chrony Beta
Udev = UltraLux Standard Deviation (fps)
Vspr = Varmint Extreme Spread (fps)
MOA values are composites at 25, 50, 75, and 100 yards

 

not as good as the old 711b from the 90s for me not as good as new CCI sv in Martini mk2 or rem 40x or 77/22 the only guns I have tried the new 711b in.
