Thread: The Six and a half Swede.

I would be switching to AR2209 for that barrel length (and drop the charge down to say 42gn and work your way up to a node).
I use 2213sc for my 28" target rifle but i never load more than 45.15gn or its too hard on the brass long term / slight reduction in precision.

I would also say, ditch any 'average' brass (like winchester or federal) you have and make sure you have good quality stuff like Lapua if you are pushing this out to high velocities.
Makes a big difference. I find Norma to be almost on par with Lapua. And regular large rifle primers seem to be better for precision than magnums.
But shoot what you got eh. its only slightly different imo.
