[QUOTE="Kennibear, post: 889519, member: 51650"] I see in his post he is using H414, the same powder as WW760. I have a developing load of 260gr AB, 79.5gr WW760, Fed #215, that clocks 3000fps+ with a SD of 9fps. This powder holds potential. The above load is maximum pressure in 375 Ruger and is shot through a 26" barrel. Read about the Magneto-Speed on another site. One caveat: hanging things on the barrel changes the accuracy. Optical chronographs allow group testing concurrent with velocity. The Magneto seems like it would be faster to set up and insensitive to environmental conditions, a real plus when things seem haywire. Pick and choose. I wonder if CFE causes problems w/ the Magneto-Speed as it supposedly may contain Tin? Have you tried the Speer 270gr SpBT? I bought a box but have to figure out a load as Speer does not list any 375 Ruger data. Keep going!!! KB [/QUOTE]
