6.5x47L, Seating Scenar 123s?

[RBD]

Have a brand new 6.5x47, and I'm hoping to take it to the local 600 yard event on Sunday.

It looks like a fairly long chamber--I believe it's cut to fit the 140 class bullets--and I'd like to start with the Scenar 123s with RL 15.

Obviously, I have a limited amount of time for load development.

What's the consensus on bullet seating for the 123s?

I also have some Berger 130s, but my shooting buddy, with the same chamber, has had trouble getting these to work, so I'm going to try the 123s.

Any seating suggestions for either bullet would be appreciated.

The 123's jump fine. Just load them with enough in the neck to keep it straight but still within mag lenght and go to town.

If you can find some RL-17. Try 40.5 with Fed 205's.
Or 120 Sierras with 38.2 of N140. Both loads touching. Safe in my rife so start lower. Stay with Fed205 primers. ES's are 75% lower than any other primer.
