I have never reloaded the 7.65, but Ken Waters did an article on it in '71. With 150 gr. sierra's he worked up to 45 gr. of imr 4064, fed 210's for 2768 mv. 174 gr Hornady rn's and up to 43 gr. of imr 4064 for 2487 mv. I am a military mauser fan. I always wanted a argentine 1909 to add to my collection, but i have never gotten around to getting one. 8x57
