I'm coming to the end of one container of AR2209 (H4350) but want to work up some new loads. To save having to restart when starting with the new container, could I pour the old stuff in with the new stuff and give it all a good shake?

If the quantity of old stuff is quite small I regularly tip it into a newly opened container of the same powder. Preferably the same batch but even if it's not I still do it. Then I shake and rotate the new container to ensure it's well blended in. Never had any issues with pressures or change of zero etc. I know it's not recommended practice but I don't wantonly waste stuff.


Hunting.... it's not everything, it's the only thing.

I do it all the time.

Never had any problems.

My powder measure has a bit left in it.

I add from a new can.

Or sometimes people use two can of the same powder and I am left with some in each.

Just add them together.

Yep you sure can.
I've done it forever with different lot numbers of the same powder without any negative effects.
Blend away my friend.

I do it with every powder I use lots of: Varget, LT-32, BL-C(2), Unique and others.

I can't tell any difference in accuracy. (Disclaimer: I'm not the greatest shot in the world . . .)

Yes, I do it, as above, and it is perfectly safe because all we are using are called CANISTER powders; meaning it is already blended to conform to a specific set of load/pressure parameters. Which is why we can use load data published.
Now, when a lot of powder is produced, they don't know how it will perform, exactly, which is also why ammo companies might use different weights of propellant.
One of my jobs was managing tank ammo; using M30 Propellant, made at Radford. Each lot required different loads. Just like we load rifle ammo, only using 15 pounds of powder.

Thanks everyone, I'll get to blending it. The old lot was only about five years old, so should be much the same.

Same as boxing paint. For anyone who has painted more than a single room…

I know some VERY good benchrest shooters that mix LT 30 and LT 32 to create 'LT 31'. They do it with 8 pounds of each in a elcheapo electric cement mixer (never used for anything else). They do it as a group and use a long extension cord at the range. They like it in their 6 PPC

And yes, I use remnants of same powders mixed together.

I read Win 296 and H110 are the same powder, I have a pound of 296 that I may blend with 3 pounds of H110 just to get a consistent batch among all 4 and call it good.

We have actually mixed different powders hoping to get better results.

We shot hundreds of rounds, baste same results as using single powders.

We use a few grains of BULLSEYE at the primer end to stop our 700 Nitro Express ammo hang fire.

Again, it works.

Benchresters have mixed VV130 and VV133 to get a custom powder possibly to get that perfect powder.
Common practice as done by many.


The only easy day is yesterday!

When SA was still under sanctions we had a very limited range of locally produced powders to work with.

F-Target shooters (who use .308 exclusively) would load their ammo with two different powders (Somchem S335 and S365).
But they did not pre-mix the powder. They dispensed the faster powder first, then the slower powder. As the loads were just slightly compressed, they should not have mixed from handling.

I did this myself for a while, until S355 came out.

One thing I will say: Some powders show quite a variation from lot to lot. If your loads are near max, it may be a good idea to just back off a little for the first couple of shots?

I have a pound of WW760 that looks like a very small amount of a stick powder was in it, looks like vargit, gun show purchase back during the peak of powder shortage and I just sit and stare at it..

Whatcha guys think? its a very very small amount of stick, start with a 5% reduced 760 load or load up 10 rounds and give to my lawyer??? shocker

That's a scary proposition.
But if its only a small amount that's a toss up.
I wouldn't buy powder at a gunshow unless I personally knew the person selling it.
That's potentially worse than buying someone's reloads...
