A tampon works wonders. It will plug a 7.62 round quite well. Tampon with super-glue will replace the sacs of quick-clot you have stored up.
Ever try to jam one into a profusely bleeding bullet hole? Not saying it wont work, but there are far more useful and effective tools currently in the box of tricks available to you. And they will work on not only bullet holes but other wounds as well or better than a swollen piece of cotton. I tell my dad about some of the cool stuff that battlefield medicine has developed in just the last few years and he just goes into a "damn we could have used that" moment (Retired Med Tech).
