Have a 7x65R - which is slightly down on the 280, 7x64 in terms of speed, but not much. Seems to be a very good round and whilst a 6lb (or 7lbs with scope) combination gun does have a wee bit of a kick, after a few rounds it is not an issue. Have used a 7x64 in a Mannlicher Model M in the past and found that to be an easy shooting rifle - weight about 8lbs. I am shooting a 160 gn Speer bullet at about 2,700 fps, or a factory RWS 162gn at 2,800 fps (according to the box). Kills noce and quickly.
