    Hi Guys,

    Looking some advice on my 284 Win build. I've told my barrel manufacturer that I want to shoot 168 grain Bergers. His reamer has .315" neck, but 0.0" FB.

    He is recommending that I provide him a dummy round to properly set the throat with this bullet.

    That's fine, however, I'm trying to determine exactly where I should set the bullet in the case. My options (I guess).

    1) I have another 284 win match barrel that has a .220" FB. Set the bullet in the brass to provide a 0.0" touching the lands with this configuration.

    2) Set the bullet in the case where the boat tail transition lines up at the neck to throat location

    Looking for any feedback from the experts! thanks

    just buy a throating reamer too and set it wherever you want. You can always cut a little more off. Putting it back on, not so easy.

    I don't DIY mine, Tim pushed it out based on a dummy if I feel I need more freebore. Having a separate throater gives you options and they are only about $75. We have started short throating reamers and using a throater to final cut for the bullet chosen for that barrel.

    .150 FB only with custom reamer, right? No way to make dummy round.

    Unless I try and get cute and seat bullet to 0.0" Ogive w/ .220" FB barrel and re-seat by (.220-.150). hmm

    You adjust the throater to touch on the 0 fb then add .150 to that.
