Thread: Reasonable speed for 300 win mag?

I was expecting it to chrono at 3,100.

I’m using 75.5 grns R22.

I use it out to about 500 yards, but would use it out to 700 yds if I really needed to. So maybe anything gained by a bit more speed will make such little difference I should be happy with what I have got?

My semi/non educated guess is the speed is pretty good.
Run it!
26" you might pick up 70? Or so fps but 0.5 MOA seems pretty good to me!
What would another 120fps get you at that range? 4"??
