why use a gun that's harder to aim? I don't get it.
A rifle is required by law to have a barrel length of at least 16 inches and an overall length of at least 24", so it has a longer sight radius, which results in greater ease in aiming.
Mangum centerfire pistols used for hunting typically have barrel lengths of 5 to 9 inches, and hence a shorter sight radius.
This requires one to approach game at a closer distance to obtain a good shot.
Its a matter of skill (not alerting the game).
Doesn't require much skill to pot a Javelina from 100 yards away with a good bolt action centerfire rifle.
