Mixing powders of different lot numbers

[Chrisyoung]

Hey I have a almost empty bottle of titegroup there barely enough in it to cover the baffle in my dillon hopper. Can I mix this very small amount in my new jug of titegroup from a different lot and still be safe. Being cheap( obviously using titegroup) I don't want to throw it out but not causing a unsafe situation or ruining a new jug of powder is more important. Thanks in advance.

That's what I usually do …   still here

Thanks jack that's what I'm going to do. I didn't think a few hundred grains would make much difference in a 8 lb jug.

I don’t even think twice. Or look at lot numbers. Same powder, dump it in.

As long as it is the same powder you are fine. I have mixed 4 bottles from 4 different lots of the same powder. Just never mix different powders.

I bought 12lbs of titegroup.  I just opened my second 4lb jug.  I just pour it into the hopper on top of the old powder.  Mix away along as it's the same powder, it won't hurt you.

...usually.

 

Solo1000 and Prima V have both had instances where they changed in velocity by nearly 10 percent at one point, when the lot # changed.

I've always just mixed them. Never had any issues.

I have mixed them and haven’t had a problem.

Usually doesn't matter, unless you are trying to meet some particular Power Factor number. 

 

For regular plinking and practice it makes no difference.

 

But I had to adjust the load when aiming at PF of 172, by noticeable amount.

Wow - Did they inform you of the change ?    If not, that would be the last time I would be using their product !!

Nope. It happens. Prima V did the same thing as soon as it got popular on here.

 

I would never advise someone to switch to a new lot # of their favorite powder and head to Nationals without verifying their velocity over a Chrono first.
