Hey all,
Looking at the very limited data out there Retumbo, or N565 seem to be the popular choices in the 133 to 135 cup & core categories.
How much faster of a powder do you all think would be a good option for the 127 HHT? Would N550 be too fast? And how does one calculate a start point for such?
One guy suggested using 140 gr. 6.5 PRC data as a reference, starting low and working up. As the case body and shoulder volume is nearly identical it kind of made sense, but why use the 140 grain bullet as a reference?
Just trying to educate myself on the process.
Thanks for any help,
Andy
