It is at least ten years since I used any factory ammunition in a .243 but having acquired a .243 Sako 75 Finnlight and having a few problems with my home-loads sooting up, I bought some Norma 100 grain to be going on with.
Whilst sorting out my home-loads for the Finnlight, I decided to put a few of the Norma factory loads across the chronograph, for interest.
I was surprised to see that they were consistently doing 2,950 fps, which gives a muzzle energy of 1932 ft. lbs. This was from a 20 inch barrel, so nipping along pretty smartly.
I bagged a Roebuck with one on Friday evening for good measure.
