I'm looking a table that I can use to change 1 powder to another 1.
I have limited funds and only a few powders to use. I found this load
the web for my 243 wssm IMR 4895 46.0 grains max I would like to
use IMR 4064. I look last night for a hour found nothig. Any help plz.
I don't know what chart you're looking at, but if it is a powder relative burning rate chart, it really doesn't let you convert from one powder to the another. One reason is that two powders' relative burning rates can SWAP PLACES depending on what round they are being used in, and the pressure levels to which they are loaded.
So to be safe, please refer to a loading table to determinre the actual starting loads for any powder & bullet combination.
For a load using IMR 4064 in that cartridge, I would recommend that you check the IMR Powder Co. website. It is likely that that new cartridge hasn't made it into everybody's loading manual yet.
