Martin are you using 260 rem datas or the specific SE ones ?
I started with swede data and they went past max to the 260 data. The swede case is about 3% larger than the 260 so you should be able to load it with 3% more powder. I didn't go that far, I went up in 1/2 grain increments and never ran into any pressure signs. The load is very accurate, 50 grs of re22 with a 129 gr spirepoint, whacked a buck lat year with the longest offhand shot i've ever made, 258 paces.
