Yes, I do have regular gauze in my kit! Again, cross my fingers.

I am conscious of the fact that technique matters a lot in stuffing the gauze, and I hardly got practice. This is on my "to learn" list (or maybe "to learn again"), but I need to cover regular first aid before considering the luxury of taking the somewhat costly courses for treating gunshot wounds.

Thanks for all the helpful information from everyone! In truth, shell casing burns (almost a certainty) will be much more likely in my civilian life. Hope things stay that way.
