hillbillybear.303 BRITISH, BALLISTICS AND THE RED BARON
THE .303 BRITISH, BALLISTICS,
AND
THE RED BARON
Last night( 12-18-2002) the Discovery Channel aired an interesting program about the final engagement of the infamous Red Baron of Germany in April 1918. During the course of the broadcast, many experts in various fields examined the known details of the battle and attempted to reconstruct it. Everything was rolling along nicely until they came to the ballistic performance of the .303 British round followed by some, in my opinion, dubious scientific experiments with computers and laser beams..
The DC employed gun writer Garry James to fire a series of test shots with both a .303 SMLE rifle and a WWI vintage Lewis machine gun. He fired both weapons at various targets between 100-800 yards and recorded the results. While discussing the 800 yard targets, he allowed that he held over approximately one (12 inches) foot in order to hit the 800 yard line. This comment disturbed me greatly. While I am by no means a ballistics expert, I do know enough about the process of shooting to doubt his elevation assessment.
This morning I ran some tables on my computer based ballistics program (Tables are attached at the end) and discovered that with a 100 yard zero the .303 service load ( 174. grain FMJ spitzer @ a listed 2400fps) is more than 300 inches low at 800 yards. With a 300 yard zero this load is more than 240 inches below the point of aim and a 500 yard zero yields a point of impact of almost 166 inches below the target. Is it just me or are these awfully long feet?
The program concluded with an elaborate computerized flight simulation and the use of hi-tech laser �guns� to investigate the probability of von Richtofen being shot down by a Canadian fighter pilot ( long the accepted version of the Baron�s demise) or to validate claims that his bloody career was ended by Australian antiaircraft gunners. In five separate attempts the flight simulator computer failed to produce a single hit( at approx 300 yards)on the infamous red triplane. Based on this series of tests the research team ruled that the RCAF pilot could not have possibly killed the Baron.( I have included a hypothetical ballistics table for Capt. Brown�s .303 guns)
The final tests with the lasers concluded that Manfred von Richtofen was killed by a single bullet fired from one of the Australian gunners at a range of 800 yards.
Based on my experience I find this highly unlikely. In my opinion the Red Baron was likely killed by the bullet of the Canadian fighter pilot ( 300 yards shooting range vs 800yds shooting range for the AA guns)) or a single well placed shot from one of the infantrymen on the scene. The ballistics of the ammunition involved as well as the battlefield setting of the engagement preclude such a shot being made with a machine gun.
Now, what do you think?
I would especially like input from anyone who has actual experience either as a fighter pilot, AA gunner, or ballistics engineer
Good Shooting,
