Bone Head Mistake

180grains/3500grains x100= 5.14%
(dumped) / (1/2 lb)

180/3=60 grains per round.
60x.0514=3.08 grains/round

That's how you figure it in case you didn't know.

You make the call.

Add to your BBQ sauce for a little extra kick!!

You will notice a change with faster powders but the slower you go, as in this case, the less change you wil notice.
The chronograph will guide you.

I've done it with h4350 and varget, load 3 test, look for pressure and go from there

Was making iced tea once and almost dumped flour into it instead of sugar, then I accidentally dumped the flour into the sugar container.....

I keep an 1lb container for "trash powder" for anything spilled on the bench or for de-milling rounds so that I do the mix powders. If I intended on reusing powder from de-mill, which is rare, I use a small Rubbermaid container.

Lesson learned, change your process and don't do it twice.

As far as using mixed powder, I wouldn't, but to each their own.

I was pulling some bullets that I loaded up for a 7mm Rem Mag that I decided to do something different with instead of shooting them. My normal load is with H1000 but I forgotten I had loaded up some rounds with H4831SC to experiment with. I had 10 of these left that I was pulling the bullets from. Without paying attention I dumped three of them, about 180 grains of H4831SC, into an open can of H1000 that was about half full. Did I just ruin the rest of the H1000 powder?

On the burn rate chart H4831SC is slower burning that H1000, which theoretically should be safe, depending on how much of the H1000 remained in the can. Personally, I would add some motor oil to the bottle of H1000 shake it up, Then I would take it outside pour it out of the can then burn it and the can with the lid off, or better yet cutting the can open while chastising myself for being such a dummy. I would then praise myself for doing things safely and not taking the chance of harming an expensive rifle, or more importantly, myself or anybody standing nearby. Better to be safe than sorry.

I'm sorry but I must disagree with this statement that H4831 is slower than H1000 at least on the powder burn rate chart that I have .Information give on this site is taken as gospel to some . That can lead new loaders down the wrong path .

For a 1/2 lb of H1000, I'd probably just pitch it. Plenty of H1000 sitting in my local Scheels shelves at the moment.

I made this mistake once too when forming cases for my 22-250 AI. My normal powder is RL-23, but used up the last of my RL-15 for fireforming. I had 4 cases fail to fire in the cold, so pulled them and dumped the powder (37 gr each) into my very full 8# RL-23 jug. Realized my mistake when I put the powder back on the shelf.

I felt sick about it for a while, but when I ran the math, the percentage was super low… I've been using it up and haven't had any issues.

Again, with 1/2 lb if H1000 - I'd chalk it up to a lesson learned and dump it.
