krw said:There is a difference between Lapua and factory Rem brass. .003" on loaded rd. neck dimension. I have 2 rifles set up to use the Lapua brass. I had PTG change the neck dim. on their 260 Rem Tactical Match reamer from .295" to .298" to allow for the thicker neck and allow for .003" clearance. I would hesitate buying a quantity of Lapua till I tried a couple to make sure they will work. I despise precision reloading for an autoloader as it does not take care of my brass as I do. Especially as good of brass as Lapua is. krw
