Military 844

I have both H335 and military surplus 844. They are said to use the same data: this means starting loads listed for 335 are starting loads for 844.
But I have found 844 to burn a little slower, and load more powder.
In other words I think 335 is hotter for the same measure, and would not use the same amount as 844; definitely less by volume.
I did work up to max 844 M193 load of 28.5 grns 55 gr fmj with no signs of excess pressure. But shooting those all day got my barrel very hot.
