Anything less than 28.5 varget the lapua brass didn't fully expand.

From my “how to thread” I used 29.9 varget / CCI450 with 105 hybrid short of touching. Shoot them at you local Saturday match. Don’t waste the components nor barrel life

What load you use?

What load you use?

Fireform load is 28.5 grains of imr4166 after a test with loads after fire form 31.1 of h4895 shows a lot of promise

I fire formed with 32.0 grains of 8208XBR and a 66gr. flat base bullet. The brass came out well and the accuracy with this light bullet was surprisingly good. Good shooting...James
