Hello all, I always enjoy reading this thread. I recently picked up 5 pounds of Re16 and wonder if anyone has any experience with this powder in the 9.3x62? I'm thinking it might work well considering the success some have had with Re17. I prefer to use the 286 Partition but recently got a good deal on four boxes of 250 TTSX's that I want to experiment with. Thanks for any insight any of you may have to offer.

Don't have a 9.3x62 but tried Re16 in the very similar 9.3x66 (.370 SAKO). Re16 is less dense than Re17 so not as much will fit in the case. The following is from a .370 SAKO not a 9.3x62: 286 Nosler - 70 gn Re16 - 2415fps (case full to neck) 286 Nosler - 70 gn Re17 - 2524fps (case less full)
So, in addition to filling the case too much, Re16 seems slower burning than Re17 in this cartridge. This might be reversed in other cartridges.
As an aside I estimated the relative bulk-density of available 4350-ish powders by filling an empty case, scraping it off even and weighing the contents.
Reloder 16 - 91.4 gn IMR 4451 - 93.9 gn IMR 4350 - 95.0 gn H 4350 - 96.1 gn Reloder 17 - 99.2 gn Hunter - 101.7 gn VV N550 - 102.9 gn
N550 gave good velocity with 250 TSX and 286 Noslers but accuracy wasn't as good as Reolder 17. Alliant 2000MR was excellent. Not yet finished working up loads with Big Game.
Cheers
I too have a 370 Sako. Used lot of different powders but RS Big Game is the best with a 250gr TSX for 2660 ft/s and the 286's(not TSX's) running ~2525-2500 ft/s in a 22.4"bbl.
