I understand your point but will the dedicated handgun .22 mags pick up steam like a "regular .22 mag? There are examples of ammunition slowing down in longer barrels. There is not much difference between the FN 5.7 and the same round in the FN "Five Seven" pistol and the P90 Carbine. No one likes the .22 mag more than I do but I would like to see ballistics of the new .22 mag ammunition in longer tubes. Buffalo Bore 75 grain hard cast FN .32 ACP in a 2" barrel gets 850 fps and 120 ft lbs. A 3" barrel gets you 1,000 fps http://www.buffalobore.com/index.php...t_detail&p=132
