H-1000 lot variation

The last time I got an 8 lb jug of H-1000 (2011) I had to drop 1 gr to get my existing velocity and accuracy back. I am going to have to get another jug soon. What is the best method of regaing back my accuracy from powder lot variation. Matching velocity seemed to work last time, is there a better method.

Thanks, Chase

I'm due for another jug of Varget and H1000 myself, sure hope I don't have to do more load development. I'm interested in this thread myself.

Re: H-1000 lot variation

Last month I finished the last of my H1000 that I bought 4 years ago - My best load was at 87 grains - Last week I bought a new jug and started shooting - I had to lower 1 gr to match what I had with my old jug - all is well...

I was going to ask this very question last week! I just ran out of H1000 and while working back up to my original velocities with my new lot, I had to stop at 91gr instead of 92gr. I wanted to get back to my original velocity so I didn't have to redo my programs and verify my drops again. Seem to be the way to go.

Re: H-1000 lot variation

LRSickle, did you get your accuracy back as well as your velocity?

Re: H-1000 lot variation

matching velocity should work if you're talking about the same outside temperatures... I know H-1000 is "extreme" rated, but even then powders can vary a bit with temp swings.

Re: H-1000 lot variation

While this may not be for everybody it works for me. I take a guess at how many rounds the barrel will be good for & buy enough powder to wear out the barrel. I buy two 8 pounders even they are different lots I mix them together. At the end of the day I have 16 lbs. of powder with the same characteristics. I then proceed to add to Global warming one round at a time.
