Hi Jim......The 6.5 saum is simply a 7 necked down to 6.5 There is nothing wrong with that except you need a long action to seat the long bullets out where they need to be. The difference in this case is, the shoulder is pushed back, the body taper is blown out, and the shoulder is changed to 40 degrees. This allows the bullets to be seated properly in the case to fit in a SA and the new case dimensions make up most of the lost capacity from pushing the shoulder back. Also, the shorter powder column should increase the efficiency a bit. Bottom line is, I believe the velocity will be on par with the 6.5 saum but will be much more short action friendly
. Also, barrel life should increase with the long neck and 40 degree shoulder. I hope this answers your questions....Rich
