I had a 20" Win model 70 Syn/Matte carbine, ltd. run in the 90s, it clocked around 2850 w/139s and max load of varget.
My 21" 700s, two of them, one SS other CM, shot 2900-2960 w/139-140s.
You won't get a speed record in a short bbl but you will kill plenty game. The 21" get loud, a 22-24 is better on the ears than an 18.5-20".
What is your style of hunting, game and range? Odds are the speeds alone are fine for killing, it's just knowing your gun, and if that gun is accurate enough to allow you to place your shot. I'd not compare, but appreciate the 7/08 for what it does on it's own.
