stx,I started at 70 gr Retumbo and once I found the most accurate seating depth, I increased powder charges until I got to 79 grains.....no pressure signs and 3380 fps is above my expectations for the 140 VLD, so I settled on that load!
Thanks for your data. I may look into Retumbo as having a little trouble finding any US 859 or 20N29 nearby and I have plenty of Retumbo. Your results speak for themselves, so hope to work up to similar success.
Also planning on using the Berger EH 140 gr. But first need to get my rifle built (26" CA barrel, blueprinted SS Rem700 action, Wyatt Detmag, MCS-T EH stock...trying to keep the weight down).
Are you by any chance running through a suppressor?
