Some people will point to short actions and say less weight, less chance to short stroke and not feed a round, and if a semi-auto its easier to cycle the action. Some people will then reply that weight difference insignificant, you should know how to operate your firearm, some manufacturers/models the action is the same, and rifle designed to work with round its chambered for.
Basically, its not a deep you fish but how you wiggle the worm.
