Umm.. no. Snapshot means a quickly aimed, short burst shot. The kind you do when are nearly compressed and diving on a low plane that Turns or Split-s's giving you time for 1 or 2 pings only on target.
F4U-C, 190 and N1k are Snapshot planes because their amazing firepower gets them kills with very few pings..and most time, those pings are from weird angles...in short, kills they did NOT work for, just quick aim and quick shot.
Convergence snapshots when you fly Pony, F4U-D or any other plane not above usually results in a quick kill due to the concentrated lead put into one place. Yet in 38, you have to pump a LOT of lead to get a kill.
