I will say yes and no to that. You can feel a bit of a hitch if that slight semi-rim case over laps the rim of the case below it in the magazine. The stronger the magazine spring the more you can feel it. Not a problem , the rim will hop over the rim of the cartridge below it. I do load the magazine to avoid feeling the hitch. I see no advantage of the 22-250 or Ackley version over the 220 swift. I takes a bunch of gun powder to beat the velocity of the mighty 220 swift by only 100 feet per second. It has been tried many times before. The pain is not near worth the gain. Remember the 220 Weatherby Rocket , 22 Winchester short magnum , 22 Cheeta , 22 Jaybird , Durham Jet ..... or 22 whatever. I read the cover off Ackleys' book. There is limit to case capacity for bore size. The 220 Swift is at the limit of 22 bore size but that is not what makes the old 220 Swift so dang good, it seems magical. It is the combination of accuracy and velocity. It defies the modern rules of short fat case design. Many years ago I've talked with accuracy gunsmiths like Kenny Jarret and Harold Broughton that have built and test fired may rifles. They will sing the praises of the inherent accuracy of the great 220 Swift. Nothing wrong with the 22-250 , it just not as good as the 220 Swift.
