Hi,

I don't have my 8x64S longer but once I have it, I loaded with 180 gr TSX to about 2800 fps. That was ha hammer och moose and boars. That load shot very accurate, aprox 4 shots sub MOA on 100 meters.
I loaded with Norma 203-B, nearly the same as Reloader 15.

Whit heavier bullets I tested out RWS EVO 200 gr, whish I loaded to 2850 fps. It's not that good precision as the TSX bullet but still good enough for hunting.

8x64S it's a killer, that speed I get in my gun it's close behind a .338 Win Mag, but with much less powder.
