I do it most of the time for the same reasons as previously stated.
Make sure the IFAK has a good commercial tourniquet (CAT/SOFT-T). An IFAK wont do you any good in your truck if you cant get to it in time. It needs to be with you or in your range gear so its close. Make sure you really know how to use everything in it. When you only have a couple minutes left of consciousness isnt the time to be taking your tourniquet out of the package or figuring out how to pack a wound properly.
If Im going out by myself I make sure to tell someone and have a scheduled time to check in or they will know somethings wrong. Read the book "127 Hours" if you think that is over doing it.
I have personally witnessed a number of severe injuries on private and public ranges (not all due to gunshots). Most due to carelessness by an individual that couldnt be stopped, some as simple as tripping and falling onto something sharp. Needing the training and equipment to treat a life threatening injury on a range, on the street or at home may not be as unlikely as you think.

+1, any piece of equipment is borderline worthless (or even harmful) if you do not know how to use it properly, but regardless of your level of training or experience in emergency care, and/or if you carry all the contents of a MEV on your back:
I know that the OP mentioned this already, but communication communication communication. Make sure your cell phone works, has a full charge, and has reception on the entire area, (i.e.If you are shooting into a canyon) Keep it on your person, not in your vehicle or on the firing line. It would not hurt to have a backup communication plan, such as check in calls (if you fail to answer or call back then something is wrong) or even a HAM or CB radio, or even a blowhorn
It is not to difficult to imagine a scenario where your primary means of communication is disabled (such as a fall) and if you have no real alternate means, your out of luck.
