Yes, .004" short
I had failure to fire not jamming 30 of 100 . I also went to cci 400 primers to fire form.
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
My first 25 rounds fireform ing 6 brAckley at 125 yds no cleaning from round one.
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
