While I know it's not the intent of the test, I'd love to hear of any IMI brass based loads that align to the benchmark loads. IE: IMI 7.62x29 loadings with same powder & bullet that duplicate the benchmark loads. I'm assuming it would be 1-2 grains lower based on my experiences.
I'm still working through my initial IMI 7.62x39 stash. I'll replace it with H or L at some point, but for now would rather spend my shooting money on bullets, powder, and primers!
Also wondering about H's comment about starting with 2520 if trying to duplicate the factory loading. Several mentioned temperature sensitivity, yet it's about all I shoot and I've not seen a trend. Are you guys just more observant or measuring better? I don't chrono often, so if that's the main way you tell that could be my ignorance.
For a bit it souned like like AR-Comp was becoming the "go-to" grendel powder, but based on the recent comments sounds like 8208 XBR is a better fit. Any consensus?
