In the comings months, I plan to unload Factory loaded ammo, then the pile of Brass will call my name to start reloading them.
I'll work up many loads that are posted here, it seems the upper limit is well established for many projectiles. When working up loads(I'll start with reduced loads), I still look for pressure signs, and watch what the chrony is doing.
When loading for the 6.8, the loads start to get warm, Swipes defiantly show a hot load. I tend to use CCI400s for the 6.8, find a good load then switch to CCI#41's. Watching for primer flattening also shows the pressure is cooking. I do feel that pressure signs happen North of 55k, and maybe even 58k for the 6.8SPC.
52k seems the level for the 6.5G, and guys are watching for Primer pressure sign's and seem to get them at the 50k to 52k level. When using the same primer(and size, small), is the size of the case head affecting when pressure signs show up, or are they the result of peak pressure. Bolt thrust difference maybe?
All cartridges are different, and I'm a little behind the curve of Knowledge for the Grendel.
Thanks in advance!
