I borrowed my club's beer gun to fill some 12 oz bottles for a contest, and I had LOTS of foam. I filled until it flowed clear and capped on the foam, but when it settled, there's more head space than you would get if you were bottling your beer out of a secondary fermenter. The beer is still in the neck, but maybe 1/2" lower than a "normally filled" bottle.
Will it remain carbonated or is the head space too much?
PS - My keg was over pressured and has been for awhile, so I am going to try to get the pressure in solution down so I can refill again if I have to.
