Agree with the Ron stuff.

The 9.3x62 is the real effiency deal. It appears to be slow to the velocity folk & it has no belt.....

My loads get 2700fps with 250gn Woodleigh (now I am weeping)& absolutely clobber wild horses & feral donkeys! On a recent trip I used the 9.3 & my .338W in similar weight rifles on the above mentioned. Similar results however .338W kicks harder! On a feral bulls the 9.3 with heavy pills was more efficient1
