I 20 odd years now and have made one mistake. I used Winchester 760 in pistol instead of Winchester 231!! Did not check properly! My bad. Did not shoot any but spent a couple of days taking apart about 500 rounds of 45ACP!
I have a collection of blown up rifles. All were donations to me. I have made a number of mistakes, but so far, nothing quite that serious.
back in the day of the balance beam scales I twice managed to loaded ammo with a 5 grain error. One too much and once too little. The too little was how I discovered a fantastic accurate load for my Hornet.
The blown up rifle have a single common theme. All were blown up by experienced loaders who made an error by loading ball pistol powder into a rifle case.
The problem will ball powder is that a number of rifle and pistol powders look similar, whereas extruded rifle powders look different than pistol ball powders.
The mistakes were made at the powder thrower. In some case the fellow saw the ball powder in the thrower and thought that he remembered that the last ammo he loaded was with BLC2. he forget the loading session for the 44 mag with the pistol powder.
But the most common mistake was emptying the pistol powder back into a can of rifle powder, so that the next time he loaded rifle, he was actually loading pistol powder, even though he was careful to use the right can of powder.
Don't say "I can't happen to me. I am careful."
Be aware of how it can happen and adopt procedures to reduce the risk, such as emptying the powder thrower when you finish the session and making a point of putting it in the correct can. (The only can on the bench.)
When I fill the powder thrower, I stick a piece of masking tape on the thrower and mark the powder on it.
