So I have some IMR-4350 (made in the '70s) that I would like to use up while it is still good. And the 8x57 is the only cartridge I reload for that can use it. Evidently, Hodgdon doesn't seem to think IMR version is ideal for 8mm, as they don't list it in their data. Lyman's "Historical Military Calibers" booklet list IMR-4350 at max load to be most accurate with Sierra 220 gr. SP, but in their 50th edition, Varget is.
The bullets I have are Sierra 150 gr. spitzer SP, Hornady's 170 gr. RN, and Sierra 200 gr. HPFMJ BT. The 200 gr., using Varget, showed promise with iron sights. Now I have a scope that needs zeroed in.
Has anyone found a combination of bullet weight that works well with 4350? The loads will be used mainly for target at 100 yds. I don't expect the rifle (surplus '41 build) to be a 1 MOA. Just hoping I can keep it on the paper.
Thanks for any info that can be had.
