[QUOTE="Greyfox, post: 846173, member: 10291"] 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.
