Re: H1000

It looks like I picked up 45 to 50 fps with the new lot of powder. The Magneto Speed is a useful piece of equipment, I don't know why I didn't get one sooner.

I plan to stay with H1000 until powder becomes more readily available.

Re: H1000

I've always had to adjust my load by a grain to match the old velocity in my edge, and now that I have a trustworthy chrony (MS) it is easy.

Most of the time, I feel unworthy to udder a sound around such paragons of wisdom- but I do have a big mouth and an additude
I know not of your MV variations, but when I read that you were using a Magneto Speed to record your velocities, a bell knocked me off the couch. I use a MS pretty exclusively now until I can get my CED M2 working like its supposed to. What I have noticed is that my POI moves 1-2 moa north when I strap the MS on. Just a guess- the MS effects barrel harmonics. Not to worry though- All the groups on all my Bolt Guns and Battle Guns are repeatable strapped on vs. off. I shoot for groups w/ the MS strapped on, and zero with it off. I will not zero w/ MS attached. I have not used the MS for OCW studies or laddering, but intend to very shortly. After I've shot for OCW and/or laddering with MS attached, I'll confirm with it off- hope it works..
As a wise old Bear once told me, " Measure twice, cut once!"

Note- My McMillan TAC 300win mag w/22in bbl eats that H1000 like it's candy- 74.5gr's behind a 208gr. Amax @2830fps- 3.43OAL (depending on meplates) I'm interested to see how the H1000 works in a McM-338LM- this one still has the 26" barrel.

Carry On-

Re: H1000

About two years ago I experienced similar velocity changes from different lots of Retumbo. At the same time, a buddy of mine experienced the same kind if change with H1000. The change with Retumbo seemed to occur about 2 years ago with a new lot producing a 50-60 FPS increase, requiring a decrease of 1.5 gr to 57.5 in my 6.5x284 to get the same velocity of 2970FPS. There was no pressure signs with the new lot using the higher charge but my accuracy peak was the same between the two lots at 2970 FPS. It seemed like a change took place with one of the base formulations that Hogdon uses in their powders. Since then, a few more different lots of Retumbo produced the same results using 57.5 gr. I have had a few buddies with 6.5x284's and a few shooters on this site that purchased Retumbo over the last year or so and generated similiar velocities using the same charge weights. I haven't had any experience with different lots of H1000 since I'm still working on a large supply that I've had for a while, but so far it looks like Retumbo has been pretty consistent since the last change a couple of years ago. I've settled on Retumbo in my 6.5 and 300's mostly because it generates about 2-3% higher velocity at similar pressures than H1000, but also because from my experiences it does appear to have been pretty consistent over the last couple of years.

Re: H1000

Does anyone have bad experiences mixing lots of powder. I do it with varget but stopped because I was worried about differnt levels of "freshness"?

Re: H1000

I first tried H-1000 in my 338 RUM years back and it wouldn't give me the velocity I was after because it was too slow burning. Then several years ago, something changed and now the burn rate is perfect. I still have one pound of an old batch left that I won't use at this time. When I bought my last batch, I bit the bullet and bought 8 pounds. I have run into similar problems with RL 22 and I quit using it, because it acted just like RL 19. The old lot of H-1000, I used to be able to load 102 grs with a 225 accubond and get about 3150 fps, with the new lots I can load 97 grs and get 3300.
