I am getting to the point that if I don't find some IMR4831 soon I am going to have to work up another load with a different powder. Pisses me off. If that happens what are the other 300 shooters using. I am shooting a 165 grain Accubond with 70 grains of powder and getting an average of 3201fps. I did try some 4350 a while back and it didn't hold the accuracy for me that the 4831 does.
