Do it once do it right!
The beauty of these is that if you dont want that specific boltface any
more just order a whole new bolt with different bolt face.
Mate of mine has the P action and shoots 223,6 BR, 6.5x47,300 WSM
and 338 Edge!1 fireing pin assembly, 3 Bolts, one action, barrel vice tourque wrench and bolt wrench about 5 min change time.
take note of changes of POI from one to another, with 1st class gear they go straight back in same place everytime.
