[QUOTE="Trickymissfit, post: 461752, member: 25383"] I use Retumbo in my 6/250AI alittle bit. The cases are fairly similar (the shoulder is a little shorter), and I'm working with 105 AMAX bullets. I'd start with 42.5 grains and creep my way upwards. (44.3 grains is my sweet spot with this powder). But my best groups right now come with 4831SC and the same bullet at just under 3100 fps. H1000 seems to also work well with the same bullet. I did some 115's, but cannot find the data. gary [/QUOTE]
