BlueZulu, Bramble or jabali Hunter will know for sure but I think it is a min 140 grain bullet at 2400fps. I'm not sure but I think the 6.5 X54 MS doesn't get this with the 160 grain bullet (in factory loads) so is considered "unsuitable" for deer (bonkers I know, Bell used it on Jumbos) but whether banned by law I don't know. Different rules apply in Scotland. My mate in kent says no bugger would have a clue if you bought in a 6.5 X 54 to hunt deer so I don't think it would be a problem, I think the RWS factory 159 grain stuff comes out the muzzle at 2230 from memory ?!, best, Mike
