I recently received a 6.5x47 lapua in a trade and have been working on some loads. Powders I am trying are IMR 4007ssc, IMR 4064 and IMR 8208xbr. there is very little data for this cartridge and even less for these powders but I like to try things that are different from the majority of others.
I done a ladder test with each of the powders. I am no expert but I think I done them the right way if I didn't I am open to suggestions and advice.
I used 123gr Nosler custom competition bullets with the 4007ssc and the 4064 powders and I used 120gr Sierra matchkings with the 8208xbr powder. If I am thinking correctly (which is a rare occurrence,just ask my wife) I should use the 37.9gr of 8202xbr charge due to it being on the same vertical plane as the shots before and after it.
I am considering redoing the 4007ssc and the 4064 and use the sierra bullets.
I am including the pix of the targets for each powder please feel free to give me any suggestions.
