Switching to magnum primers for 6.5x47 Lapua??

[PharmShooter]

I took delivery of a custom 6.5x47 Lapua recently. I've got 100 rounds down the tube and have setteled on 37.9 grains of varget with an average speed of 2835 fps using CCI BR small rifle primers and shooting 123 gr. scenars. I was able to get my hands on a couple thousand CCI 450 magnum primers.

What do you guys recommend I do with the load if I switch to the magnum primers?

Thanks!

Work your load back up from below with the newer, hotter primer. Change a component, rework up the load, is Reloading 101....Shortcuts are usually a bad idea.
