I found the device to be slow to use but to give 100% ignition with pyrodex. I had a good deal on rws caps that gave 70% ignition or so and were only 2.98 per 100. I could buy primers for 13.99 a 1000. This gave me the ability to go shoot with components I used already and get good ignition when I couldn't get real BP. THis was with a TC Hawken. Gianni.
