I shoot a factory Weatherby Vanguard with a 20" barrel, 1:14" twist. I usually use 55gr VMAX/SP (the 50rd box from Cabela's) but I have no chronograph so I couldn't tell you speed.
I've shot only out to 300yd, under 1.5 MOA consistently without a problem. I'm no JG nor do I compete, but if you're shooting for fun or hunting with factory loads, my rifle is a testament to 20" being good.

I believe you'll lose about 40 fps / inch in the .22-250 with heavier bullets, and about 50 fps / inch with the lighter ones. That's figured on average losses with 77 and 50 grain bullets and barrel lengths from 24 to 16 inches. The worst aspect of a shorter barrel in large-for-caliber cartridges is the muzzle blast, IMO, but if you're going to run a suppressor it won't be terrible.
