I bought back this rifle after about 18 yrs. I sold it to a friend who pasted away 8 yrs ago. It shoots real well with most factory stuff but I want to reload for it. I'll be using 165 gr bullets. Looking for suggestions on powders for best accuracy in the mod 70. Been trying IMR 4064 with only good results with close to max but not great. I have Hornady 165 sp, btsp, Nosler 165 bt and partitions. If you have any ideas let me know.
