With RL17 you can't just plug it in to the burn rate chart and carry on as usual.
There's a fundamental difference in the technology applied to the retardant. It's impregnated through the kernels, not just layered on top.
This changes the pressure curve in ways that I am not smart enough to explain in technical terms, but it essentially slows the rise of pressure, and extends the peak pressure. Basically you getting a longer "push", on a bullet that has already reduced more inertia.
And do you think that Quickload developed pressure "calculations" keep this in mind?......................DJ
