Need data for 300blk out loads

[DEADEYE1]

Was curious if anyone has any load data on a 300 blk out for 135 GR HP VARMINTER sierra bullet # 124. Will be shooting out of a 10.5 SBR.
Thanks

if not no biggie I can work my own up. I was told by Sierra to use the 150 gr load data and start with the bottom end and work my way up in .2 grain increments.

just asking green screen is all
