Dumb question about dummy rounds.

[Kenny474]

I am setting up some 6BR dummy rounds to have my reamer ground. I have a few questions about how I should seat the bullets, as in which to use and how far in to seat.

I plan to use either the 105 A-Max or 95-105 Berger VLD, or possibly 95-107gr SMK's though I would prefer the others. If I am to shoot both, which should I use to set up my dummy rounds so I can reach the lands with plenty of bullet in the case? And should I seat the bullet with the bearing surface all the way to the bottom of the neck?

I don't have any 105 A-Max's yet to measure, as they are on order and will be in later in the week, but I would think they are of different dimensions and will be a bit different in seating length to hit the lands.
I figure someone here will have a good answer, as many of you probably have done this many times.

Thanks

Kenny, actual bearing surface length using two .240" comparators.

95 Berger VLD .279

105 Berger VLD .342

105 A- Max .427

Just to show the large bearing surface variations between the different pills. the A-Max are huge.
Note most of these pills are fairly old. Especially the 105 Bergers, they date back to a time before Berger printed lot numbers on the box.
