Question for the more knowledgeable regarding variation from lot to lot. I have 4 different batches of W760, I'm thinking to save time down the track that I just mix them all together. Anyone got some advice why that wouldn't be a good idea?
Would obviously need to work back up to my current loads that use it.

I had some mixed lots of powder so mixed it really in a new, clean bucket then filled the containers back up. My theory then is I now have the same powder lot in each container & wont have to adjust my amount until I exhaust all the powder. Seems to work really well for me so I practice this for all my powders now.
That's my thinking
Yup I have done this before for the same reason and no issue at all just work up your load to confirm once mixed :thumbsup:
It's not an issue to mix batches. One downside is you open sealed containers earlier than you otherwise would, which isn't an issue if you are going to use it all in the near/medium future
How long you think a original sealed bottle can be stored for?Quote:

No noticeable difference in speeds and accuracy.
This is what I expected as 2208 is one of ADIs biggest sellers and therefore most manufactured.
I expected that ADI would be able to control the manufacture to give (almost) identical performance.
Test your blend, work up your load. Have fun.
Should do 10 years at least if stored correctly.Quote:

That may be so but there seems to be general agreement amongst serious US target shooters that H4350 (2209) does vary between batches. That's why I blend mine into one big lot if I get different batches round about the same time.Quote:

Indefinitely is the answerQuote:

Unless it is clumpy or smells bad it is good to go
I have never found any variation with 748 or 760
I keep mine in a chillybin to reduce temperature fluctuations, an old fridge probably does the job better.Quote:

Inevitably it is just out of sync with each bullet batch and each primer batch too.
I try to use up all of one batch until there's less than one cartridge load left, then move to the new bottle and mark the projectiles with felt pen, then try and shoot them off together. I count on the different batches being very similar but like to re sight in pretty soon after changing each batch of any component. Not OCD about it though. In theory different batches could give enough difference in velocity to affect long range (600+yd) trajectory for F class or TR shooting like cyclops is talking about, but for hunting it would be more a matter of harmonics and a zero change from that.
I try to buy powder in at least 1kg at a time to minimise this problem.
Why did you buy more and start more before you'd finished the last batch ?
Only one of them is open @Bagheera. Use it in 4 different loads so picked more up when ever I could.
I've never had any difference in performance between 2208 batches.
Great powder.

My standard practice goes something like;
buy a pound (500g or a kg if that's all I can get)
Do load development, once I get to a point where I know I'll be using that powder even if it's not a final load then
Buy a couple of years worth in as many different batches as I can find.
Mix all the batches together then put them back into original containers.
Check load is still all good, sometimes I'll start lower if I'm on the upper limit of pressure.
Once I get down to about 6 months supply I'll buy more and add it to the bottle, I don't bother changing loads as I figure it won't change much now.
This approach has worked well previously as with a few phone calls to different shops and a bit of driving to pickup powder initially I'd have a few batches and could then just get the local store to order a small amount when I needed it and didn't have to workup loads again.
Over the last 18 months I've run into issues with only reordering with 6 months supply left, by the time I get the new powder I'm all out or the mix is to low and the new batch of powder changes it.
I also couldn't get any more of the powder I needed after finding a good load for a new rifle, I'll end up just getting a lot of the next batch of it to become available and have to rework loads.
OK, so you’re mixing batches because you cant locate enough of a single batch in a short space of time ?
I have just finished this in loads for my 243. Got it for $20 about 4 yrs ago and sat on it. Tried a couple of calibres, 243 loves it goats not so much. I'm guessing its 60yrs or so. On the back, bottom left of pic, it has R33/9/26. I'm not game to say that means 26 Sept 1933 but hey. @grandpamac might know lolQuote:

GPM.
Im going to agree with you on the date being 26th of 9th 1933...... just because it makes the story all the better.
