I made my own "slixshot" vented nipples, and found that the pistol works "okay" with the CCI magnum #11 caps, of all things. I can get through five rounds without jamming if I flick the pistol up and back when cocking it. There is still some hammer blow-back. I bought this pistol to serve as a smaller, lighter, small game gun/wilderness survival gun. I have some buyer's remorse, as it just does not feel "good in the hand". But, it is light, and I sure can't argue with the accuracy. It shoots about like this with ball or bullet. It seems to be very consistent. I'll be packing it with the bullet, as it's much more easy to re-load it with a lubed slug, in the field. I had planned to use it with ball, as I could carry more ball for the same amount of weight. Using a ball requires fiddle-fidgiting a wad into the chamber, which also requires carrying the wads somewhere. Anyhow, I think we are good to go. It's not a "bad" pistol. Sure is pretty. Powder capacity is limited, using 15 grains is about it under a 130 grain slug. I suppose one could fit 20 grains under a ball, with a very thin wad. This group I loaded the Outlaw Kid style wad(s) just for fun, and I barely got the bullets to seat deep enough. Not sure why I did that, the LEE bullet has two lube grooves, and carries enough lube. But you can see it didn't hurt accuracy. Well I might try 15 grains of 4fg to boost velocity a bit, in case of Wolf attack, but the 3fg load should punch a hole in a wolf, and again it's a small game gun, not a wolf gun, as is my Remington Navy. Or Remington New Model Army in Navy caliber, or whatever it is. !!! Thanks for listening.
