Of course it's pushing them. Well at least the 2,900fps loads are. 2,784fps isn't. They have been pressure tested and I am perfectly fine with the results. Others may vary.
I'm at just over 1,500 Juggernauts in the last 2 months or so. I highly doubt that I will ever shoot 155's again.
"Pressure tested" as in "I've fired them in my rifle and it hasn't blown up yet"
Or
"We hooked up a piezo and it registered at 63K"
Big difference between the two...
