Ok, someone asked me if I had any data on the 8mm Mauser cartridge and I have been tinkering with this one for a long time so I said that I could put some on the forum. This is data for the .323 dia. 8x57 Mauser and should not be used in the 8x57R, or any .318 dia rifle using .323 bullets (duha, right?) All the data below was created using my K98k Mausers and the velocities verified by recording multiple shot strings (5 or more) and averaged. Ok, so here we go with some of it and I hope to have some actual results using H414 very soon.. Enjoy:
