I think the Swede is just so very versatile, that most powders in this range function wonderfully. I've used the 4350's and 4895's (imr & h) with partitions, interlocks, ballistic tips and now accubonds, also, and the accuracy is basically indistinguishable between all components once the proper charge-to-bullet was found. I love this cartridge. I also believe not having a chronograph has helped, somewhat, as I know the velocities would probably not excite many, and could quite possibly disappoint and ruin an otherwise very effective load in the mind of this shooter. It (chrono) is still going to be my next purchase.
JB, can't wait to try the Ramshot Magnum! (Though I've been spoiled by the lighter charges necessary for the 4350's/4895's).
