Seems to me the 7.65X55 Argentine (Peruvian Mauser M98, not the Model 91 Mauser) can be loaded about duplicating factory .308Win., but it's been a long time since I've had anything to do with one - ie: 1976. My late 'best' buddy, Lester H. Hawkes had one - long barrel if I remember correctly.
My data (Pacific) shows 150's at 2,750fps with IMR powders and 2,920 with Norma 201. 175's are loaded to 2,570fps.
