load data 300 RCM

[singleshothunter]

Hello,
New here, so Hi to all.
Im looking for load data for 300RCM for 168 e tip bullets for
H414
IMR4350
H4350

Or any others that are not in nosler book. Yes I am aware to start at beginning load and stop at med range, all the while checking for sign of high pressure.

Thank you
