Years back, I bought a .454 Alaskan. Soon after, I realized that I was experienceing a 30% velocity loss, over a chronograph, when compared to a 7.5" barreled SRH. It was surely shooting a .454, but with nowhere near real .454 power levels. This will hold true for any snub nose fill-in-the-blank revolver.
We tend to buy guns for a particular purpose, but really, "like" is as big of a factor as anything. The Alaskan's are all selling a good bit more on like, than on fitness for a particular purpose.
The dozens of scenarios that we, (me too
) Tend to mentally project for defensive firearms use in the wild, are funny some times, the best one is that a 6" barrel is to slow to bring into action vs a 2.5" barrel. Best -
