EKM: I guess that we might want to focus on the basic moral imperative: Regardless of the weapon, we owe it to our prey to be proficient with whatever we bring into the field. We all have different life situations and varying degrees of ability to have multiple weapons and the time to use/practice with them. I' m a bow/rifle/shotgun hunter (and occasionally slingshot) They are tools. If you work on vehicles, or perform carpentry, you have to be proficient with a variety of tools to get the job(s) done well. This means working with all of them frequently. Weapons are no different. ...and yes, I for one find that I get " rusty" with one or the other, except for high powered rifle which seems to be instinctive regardless of which cal. The slingshot is the real challenge...
