I have not used the Swift A Frames on DG however I have shot 15 head of plans game with the 300 grain 9.3 A Frame from Springboc to Eland and could not ask for better performance. As for the Rhino bullets, one of my customers has had dismal bullet failure with their 286 grain bullet in 9.3. He was pushing them at around 3100 fps and the hole front half blew off.
