Seekins PH3 7 PRC Reloading Question

[Nova]

I just purchased a Seekins PH3 in 7 PRC and I'm getting ready to reload for it. I figured I would start with 20 thousands off the rifling lands for length. What do most of you start with?

Thanks.

Depends on the bullet but it's a good place to start. I started at .020" and ended up at .030".
If using Barnes bullets, they say .050" to start.

I'm starting with Hornady 175g ELDx. I did buy some Barnes 160 LRX to try at some point.

I think I'll start at 0.020 off the lands for the 175g ELDx and go from there.

Thanks for the help!
