Re: 700P 20in barrel ?
I'm getting 2,635 fps with 168's out of my SPS Tactical...and that's not even a max load (no moly'd bullets either)...if your scope has at least 45 MOA of "come up"...1000 yards should be no problem as long as you, yourself, are up to the task...the rifle can do its part.
Factory loaded 168's are around 2,550 fps...I have not used any 175's yet.
