Can you please give me some suggestions for reloading 303 with IMR 4064;
I need starting and max loads as well as OAL for the cartridge.
125 gr ProHunter Sierra
174 gr FMJBT PRVI
Thanks

Imr3031 is what I use but for the 125 starting load is 41.5 and max is 46. 2.900 OAL..need to get you several manuals. The 174 start 37 max 41.5 and 3.075 OAL..always check to make sure you aren't in the lands and you should be ok in length if you don't have a cannulure. If old Enfield SMLE don't use hot loads as they vary greatly and trim all your brass to 2.212

Thanks for your reply Sir . I have only 3 -1 lbs IMR 4064 (All unopened) I was able to find data for 3031 and Varget but not for 4064 though .

This should get you started. I would just start with the max 150 number for the 125, and use the 180 data for the 174.
