H1000

Has anyone using H1000 had big swings in velocity when changing batches?

I shot yesterday and went up 3 1/2 minutes from my previous day of shooting. The only difference was I opened a new can of H1000. I weigh every powder charge on a beam scale that is zeroed before I start the reloading session.

New Remington Brass
91.5 gr H1000
CCI 250 Primer
300 gr Berger OTM

Seated to jump .025

    I haven't had to switch batches yet, but I am nearing that point. That was something that I was worried about, but 3 1/2 minutes seems like a lot! Interested in seeing if anyone else has seen a difference that big. How different were the conditions when you shot last and shot this time?

    Yep, went from 2875 fps to 3001 fps the only thing that changed was a different lot of powder. I really liked the higher vel. but knew it would not last as I only had 1 lb. of that lot. So I opened a 8lb jug added the 1lb. mixed every thing up on a shaker really well. I'm now shooting 2985 fps. got all my drops worked out, and am good to go. The funny thing was with the higher vel. my groups remained very tight, sub .25 moa. The only thing that changed was POI. Readjusted scope and all's right with the world. Well not really I guess O'bummer is still squatting in the White House.

    Each batch is different. I was in the same boat yesterday except mine shot slower. Old keg of 1000 I only needed 91gr the new keg looks like I will need 92 or 93 grains to get the same fps.

    Yes it's very inconsistent lot to lot that's why I quit using it....

    3.5 MOA seems like a lot of adjustment for a new batch/lot of powder....but I have experience velocity changes with different lots of H1000. That is why I went to buying 8 lb. kegs. You get a break in price and assure consistency for hundreds of rounds.

    +1, there is more to the story and I am sure you will have more to report after you look further into it. 3.5 moa was not the usual 20 0r 30 fps between lots. The zero had to have 2 or 3 moa difference too.

    Buy large lots if possible, I also blend them if different. Then once dialed in I am done. The beauty is if the temp is 40 degrees different you will still be on. Not like some powders I will not mention. Just ask Gary about his experience with the temp sensitive powders and his 100 fps swings.
