Just a suggestion on reloading for others.A friend asked me to load 500 rounds of .44-40 for him several years ago. He supplied the components, and TiteGroup is what he brought me. I found it didn't meter particularly well, but I got his ammo loaded. I doubt he ever shot any of it. There was a good bit of Titegroup left over and he told me to keep it for my labor. I still have it...
There could be a liability issue in which you could be exposing yourself! Should a double load get dropped and the gun blows up, it would not be fun for all involved or close to the area.
We assume the liability for our shooting reloads that we create. I am not afraid and have done such when friends ask about them giving me brass to reload, to say NO I CANNOT DUE TO LIABILITY ISSUES.
Things can happen when you least expect it. My brother had his son-in-law with a new Sig 45 ACP, in which he used loads that he created for his 1911. None the least and he does not know what happened, but assumed a double charge was dropped from his Dillon 550B in a round and a $800 gun was destroyed or badly damaged to be non functional. No one was hurt except (thankfully) for nerves and scare the Willy's out of each of them. Brother purchased a new one for replacing the pistol.
However, just a thought and suggest to place forward for your digestion!
Best to you!
