I haveead thistopic. I think there was a mistakein the naming of the 300Win mag. the factory loads for the 300h@H mag makes more since. the hienergy loads for the 06 and the hornday light magloads out preform the 300 H and h "holand and holand" not the 300win mag in my blic. charts some of the hi eng 06 ore close to fact standerd 300 wmbut the win mag betats it out but on the other hand the Hi eng loads do out perform the 300 h @H but only slightly
