See the 6.5x55 thread in the big game section. I have not used the Sirocco but for other 129-130 grain bullets 51.5 of R26 is starting to look like one of those universal loads that seem to work in a number of rifles. Proceed slowly as the Sirocco is a long bearing surface high copper content jacket bullet that can elevate pressure over more conventional bullets. I understand they can be picky on the seating depth acting some what like a VLD with either hard on the lands or off to way off working better. In other words don't write them off too soon if that is what you want to shoot. Good luck.

MRP, R22, 7828 and several others all work well in the Swede hard to find a bad combo with most rifles.
