TA-DA... it works! Works VERY well! It holds the first pump and each one after. Dry fired it and after about 5 cycles dark / translucent oily mist started appearing out the muzzle. 5 more cleared it up for the most part. I no long had the bleeding out the caps, but I knew the oil was making it's way out, and it was translucent, not dark black. 5 shots with pellets and while she's a strong shooter it still wont dump quite all at 6 pumps... but she is sealed back up and CLEAN inside! Honestly I hope just shooting it regularly will help now.Next, I'll strip the wood and refinish it and call it GOOD until it gives me trouble.
