The subject has been discussed at incredible length in the AR forum with regards to 5.56 ammunition and barrel length effectiveness of various AR types.
In the AR world, SBR's suffer from terminal balistics challenges due to the shortened barrel lengths vs. the minimum length requirements for the gases to expand, delivering terminal balistics over various ranges.
Anything shorter than say, 16", and your ammo choices for your SBR's become rather important when considering the loss in power due to the shortened barrel.
My question is this. I never hear this being discussed in the handgun world and I'd like to know why.
Is it simply because the ranges one typically uses a handgun in self defense are usually short enough that barrel legth and balistics becomes an irrelivant factor?
Would a snub nosed .357 effectively have the balistics of say a .38, when an 8" barreled .357 would keep it's .357 balistics over a greater distance? Or is handgun ammo an entirely different creature where such considerations are unimportant?
Just curious as to how this is actually viewed. I'm thinking the useful range most handguns have is so short that the ammo is effective as the caliber it's advertised as, as long as you're not shooting beyond 25 yards.
Anyone care to enlighten me?
Thanks.
