Heck we have all done something similar or worse at one time or another shooting these thiings. The way I get around that now is to not do things as single shot, but to put out 5 loads at once (I have 50 speed loaders)

5 loads of powder
5 bullets
5 sabot
5 primers

I then, pour the powder in the gun and if someone interrupts me and I don't know where I am in the loading sequence, I look at my lined up bullets, powder sabots and primers and I see that my power has the cap off, so I know it has been put in the gun and I have 5 bullets left, 5 sabot and 5 primers, so I know I have only put the powder in. If I had 4 powders, 4 bullets, 4 sabots but 5 primers thenthe gun isall loaded, but have not put the primer in yet---I never do that until I walk up to the shooting bench. Keeps things simple. If you shoot groups of 3, then lay out

3 speed loads
3 bullets
3 sabots
3 primers.

If you only lay out 1 load of
1 powder
1 bulet
1 sabot
1 primer
and someone interrupts you, how will you absolutely know if you were putting your powder/bullet/sabot/primertogether or placing the things in the gun? You won't,'cause we are all fallable humans, we must work toward safety in design of our procedures, protect ourself from ourself--we are our worst enemy, not someone else.

Now lets say semi, follows this system and he shoots and it goes puff, no bang. He looks at his stuff he has left and he sees:
5 charges
5 bullets
Oh, I must has shot with nothing in the rilfe.

Or lets say he puts the bullet down and don't place the powder. He shoot and it does puff. He looks at his left overs and finds
5 charges
4 bullets
so he loaded the bullet without the charge.


So lets say he places the charge in and doesn't place he bullet in and sees no hole or it don't kick much. He counts his left over loads and he has
4 loads
5 bullets, so now he knows the reason that the gun shot so light.

Hope this helps someone be safe.
