Load data 6.5x47 Nosler E-Tip

[BillyGoatMachine]

Does anybody have a baseline on 6.5x47l using Nosler’s 120 E-Tips and Varget? I need to get a load together quick for Saturday’s rifle opener.

My quickload does not have the 120gr etip, but here are a couple others for comparison:

I would load 3-5 rounds at 3 charges (say 36, 37 and 38) and go chrono them and then see where they land for velocity/pressure in the 3 simulations above.
Then I would adjust my load based on what I found.

[RugerNo1]

No quite the same bullet, but up to 37.4 grains if Varget with 123 SMKs was good to go with no pressure signs in my 6.5x47 chamber.

3.7 col. which was kind of short for my chamber. 1000 yard groups looked good though!

[BillyGoatMachine]

Thanks guys. I ended up starting with 36.0 and up to 37.0, with 36.0 showing signs of life but I need to go back and repeat.
