Testing working-up loads for my .260 this afternoon. Sierra Prohunter 120 grain bullet from a 20 inch barrel.
43 grains N160 posting 2,670 fps with a maximum spread of 32 fps.... then the chronograph packed up !
I have fired a few loads of 44 and 45 grains of N160 and all seems fine, with no signs of excess pressure at all. Speer gives 45 grains as the maximum load for their 120 grain bullet.
I have managed to shoot an inch and a quarter group, with the 45 grain load, using a 6x42 Swaro scope with 4A reticule, so plenty good enough for stalking.
Could someone tell me what quickload gives for 44 and 45 grains N160 please ?
