According to Taylor, the original loads of 2,175fps with both soft and solid 286gr. killed just fine and did not need the update to 2,340fps.
What is most interesting about these ballistics, is my Model 46 Husqvarna in 9.3x57 made 2,170fps with resized 300gr.RN's and 2,200 quite easily with 286gr. & 2,300fps with the way too soft 270gr. Speer SRN.
