    How much different is it? I noticed they have data for the 8mm rem mag using h100- but not retumbo? But they list both for the 264 win mag. I don't know if its because test rifle 8mm had 24" and 264 had 26"?

    It's tough for anyone to list every possible combo for a load and also both H1000 and Retumbo are better choices for a 264 Win mag than they are for an 8mm Rem mag.

    I don't know. I've never loaded for a 243.

    Retumbo is a bit slower burning.

    isn't retumbo just h1000 with a coating extra coating for a slower, cleaner more stable burn?

    H1000 and Retumbo are two very different powders. That being said they are excellent powders. I use H1000 in my 7STW with 140-145 gr. bullets. I use Retumbo also in my STW with 180 gr. bullets. H1000 is okay with 300 gr. bullets in my 338 Lapua but Retumbo is better and US869 is better yet. Try them both. If you know someone with quickload they can get you pointed in the right direction with Retumbo and your 8mm mag.
