When I used to hike the deserts I would always carry a shot capsule load in the first two chambers coming up and a couple spares in my pocket. I would load them for 45c, 38/357, and 44, usually with 7 1/2 shot but occasionally play around with double ought with filler in the spaces for the larger calibers. I found them to be very effective on snakes, horseflies, and scorpions. I also found they are very fragile and it doesn't take much to break them, either jostling around loose in your pocket or trying to find the right crimp and forgetting to change out the seating plug in the die. I usually used a very light crimp, didn't take much and a taper crimp works too. Unique was my preferred powder and I pretty much followed the recommendations listed on the side of the capsule box. You can play around with what works best for you, the most you'll do is make a mess when you break a capsule. I never had any caps that didn't fit snugly, but the glue is a good suggestion or nail polish in clear works good too. Keep notes on what you did so you can refer back to it if you are doing something besides the recommendation on the side of the box.
Good luck.
