62-67grs, caution some manulas have a couple grains shy as listed max so proceed slowly and with caution up the latter. Once you see any pressure signs stop and work below that mark to find the sweet spot. Also if your at the top of the pressure curve with your load back of 1-2 grains in the summer heat. Personally haven't used a ton of 7828 in the rem mags but have incurred problems with a 300wm load that was safe but warm in spring and sticky in the dog heat of summer. I have heard others say they same about 7828 in rem mags and stw 7's.
I am going to try H1000 this year just to see how it fairs. It has gotten some good airplay on other forums with 160 class bullets. Problem is the max thrown out are all over the board to 66grs by Hogdgon to as high as 73gr. I think 70-72 appears to be the common ground with experienced reloaders, so i plan to work it up slowly from 65 - 72 ish or till I acheive the 30-31K &/or pressure signs. Retumbo is also been a thought of mine but it has even less data published to go on. Sorry off your topic
...good luck
