i am getting ready to load a bulk of 308 with imr4064 and just wanted to know if anyone has found a sucessful load for it used in a standard m1a. i am planning to use either 168 or 173gr bthp. i really didnt want to use 4064 but that was all i could find 6 lbs that was suitable for use with a M1A. I have had great sucess with 4895 in the last bulk loading i did but it seems at the present time that its unavailable. So have any of you had sucess useing imr4064 so i can try that first and maybe save myself a little time?
