Really now. As I understand it, most encounters with goblins involve participants within a very small amount of distance. One does not need "range time" to hit someone 5 to 10 feet away.
And you're out there shooting targets 20-30 yards away you're planning something that's going to put your a## in jail.
Statistics: Criminals hit with less than 10% of "aimed" shots with a pistol. Police hit with 23% of aimed pistol shots, when you only count shots at a person in a gunfight. Civilians defending their homes hit better than fifty percent of aimed shots (warning shots excluded, of course). Even at short range, practice and familiarity matter. Most of my pistol practice is at the maximum expected engagement range of 10 meters - my range time is for home defense, not for things that will cause unnecessary trouble. BTW, the aimed use of a shotgun hits around 80% or more of the time, and it incapacitates on the first shot in nearly 90% of hits. I know what I am training for in the 90% of my practice that is with a pistol, and it is not long range (although I do love rifle practice at long ranges).
