after doing a little digging I found some people that swear by 40GR of IMR4895 powder for the 128gr bullets. another listed is 36gr of H335 for the same bullet weight. you could also try 36gr of IMR4064 as it usually makes for quite accurate loads for several milsurp cartridges. you may have your LGS load a few of any of those recipes and see how it fairs, you could also back off a couple grains if you dont feel comfortable with 2nd hand load data, I've had people tell me a load and ended up finding that they were 25% over recommended max in some manuals.
