i have shot three loads in my custom 260 , i am using rem. brass,nosler 120 gr ballistic tip bullets and fed 210m primers. the three loads i have tried are as follows:41.5gr - 42.5gr - and 43.5gr.the 1st load with 41.5 avg. was about .5 , with 42.5 the avg. was just over.3 , then with 43.5gr the groups really opened up,to about 1.2! i am a little nervous due to my chrono taking a dump . i dont have any pressure reading equip. and my brass is well used,so its hard to tell whats going on.i have a new chrono on the way and will post results afterward if anyone is interested.
