Hi guys,
I've got a .308 load which is great with 2208.
Separately have some 2209 and 2206H from other stuff that's no longer used.
I want to put the powder to some use, just not to waste it, but there is no point doing proper load testing because I wouldn't buy either of the powders again as the .308 load is perfectly fine with 2208 and I'm sticking with that.
Rather then just load a batch of whatever and get ??? results, is there a rough formula of sorts that goes along the lines of
43gr 2208 = 42.3gr 2209
and
43gr 2208 = 44.1gr 2206H
Those numbers are made up, just an example, but asking the question in the hope of guestimating a reasonably accurate load with the two powders based on what I know works with 2208 rather than just load for pot luck.
