I did keep my .45 cal pistol load for a few months. I loaded it because of a wave in crime in my town, and to show my mom how to load the gun.
I forgot to take picture of it. So I loaded the gun with 35 grains of 3fg black powder, with a simple ball and patch. I did lube the barrel, which I later found that to be a mistake. When it came time for me to shoot it, I fired alright, but the smoke, the noise, and the shot was all very weak, and there was very little recoil. :barf:
in fact the smoke kind of shot out like stars in a fireworks show.
So the lesson is simple. Make sure that the barrel is dry. I would prelube the patch and let it dry out for a while, to make sure that there is no or very little moisture on the powder, and keep it the gun in a dry place. For me I did keep the cap on the nipple but made sure that the gun was in a small box, so that if it were to fall off the end of something the gun should not fire when it hits the ground.
After I unload and fired the gun for the first time, I was sure that 35 grains of bp wasn't a real big deal in the gun. I knew it was loaded for a long time but I figure a fresh load wouldn't be any different or that much off :shake: Was I wrong or what.
BOOM the smoke was heavier, the shot still missed it's target, but I could see the large hole it made on the soft soil, and my hand was killing me! I now use 20 to 25 grains for practice shooting. It kind of sting on 30 grains.
But you get my point. Be careful when keeping it loaded for a long time. I had this gun loaded for more than 5 months. :nono:
