I have a Turkish Mauser that has been sportered, and have been hand loading for it from the start. The best powders I have used are IMR4064, Winchester 748, and Varget. I have loaded Hornady 150, 170, and 195g bullets. The 150's at 2800 fps, the 170's at 2630 for deer hunting, and the 195's to around 2550 fps. I only neck size the brass, and have had very good accuracy with all loads. Hornady has loading info for higher preasure loads, and there is a lot of info on line. I am in the middle of moving, so all my reloading information is packed away.
