Re: Now what am I doing wrong...moisture??
There are alot of possible reasons.
reliable fast ignition requires almost [censored] consistency in loading and priming. Pour the powder the same way, rap the gun on the side to settle the powder into the flash channel the same each time, line the patch up the same each time, ram the ball home against the powder with the same pressure, each time. I suppose the powder in the flask may have absorbed enough moisture to cake up, and not flow into the flash channel, but I have never seen that happen. Since it is only a 50 caliber, you might fine that 3fffg works better.
