Wow, that's a long, heavy bullet if I'm converting my grams to grains correctly.
I get about 210 grains, which seems to fit with the velocity you mention. Do you always use such heavy bullets, or is that just for moose, I mean elk?
Common wisdom here is that about 11 grams is the most efficient weight and nothing more than 11.7 is really needed, even for heavy game.
13,7 grammes it is special hunting bullet for big game Elk (moose) and bear.
There are bullets 11,7 grammes for deer ,for small deer.
There are bullets 9,7 grammes for snaiping or for wolf .
"small deer" I mean roe roebuck Siberian Roe Deer
