Another day on the range

 One item I may have to rely on, one that I practice least with, is the shotgun.  I had mentioned before that, on returning from New Orleans in September '05, my first purchase was a Remington 870.  Another 12 gauge in the house is a compact 'coach gun' which, although limited in capacity to 2 rounds, disassembles into two compact parts facilitating transport and secure storage.  This gun I had kept in a small safe at my 'home away from home' work apartment, configured as illustrated.

 Now done with the apartment, and having spent three range days recently with the 870, I though to look again at the likely effectiveness of the side by side with either 4 Buck or the larger 0 or 00 Buck load at the range near home.  

 The gun has two triggers associated with a modified choke barrel (right) and full choke barrel (left).  One round of #4 buck and one 0 buck was fired from each barrel at both 10 and 20 yards.  The results, from this gun/ammunition combination at least, demonstrate that 'just because it's on the web don't make it so'.

Example:


"50 yards"?   Possibly lethal, certainly dangerous, but 'effective'?

    


Lets see what we got:

4 buck at 10 yards?  Certainly a game stopper. (circle is 9 inch 'plate' outline)



But at 20 yards?  Even full choke 0 buck spread is opening beyond the plate.



The math is interesting (acknowledging I used advertised muzzle velocity at 20 yards for the calculations).  Click to see larger.






Two observations: 1. choke made a significant difference in pattern density.  2. even the larger 0 buck at 20 yards with the Remington load and full choke was delivering only 6 of 12 pellets, each with roughly the equivalent of .22 LR energy in a 9 inch circle.   Adequate to instantaneously stop an armed assailant from firing his weapon?    Depending on pellet location ... maybe.  #4 with modified choke or less at 20 yards?  Drawl your own conclusion.   

So, little surprise, buckshot, 4 or 0, or likely the slightly larger 00, is significantly range limited.  Likely much more so than some advertisers claim.

BUT - across the span of a small apartment?  I expect it would have served.
