Lots of good choices already. I would skip R-17 and go for R-16 if enough will fit in the case, better temp. stability and de-coppering agents. I would also take a look at Stay Ball 6.5 even though I hate that name choice, SB 6.5 has all the required features and good density too so you shouldn't run out of room in the Savage. R-26 is worth a try for the heavies and if you are not going to shoot in really hot weather. Just shot some 243s at 90 degrees and no problems but had fits with the 6.5x55 at 100 degrees.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
