Guys, I'm considering a build in .338W (338/7BR). I'm so new to this idea that I don't even know what to ask.

Here's what I'm looking for out of it: Longer range accuracy (500-600 yards minimum ideally- never opposed to reaching farther though), primarily subsonic suppressed shooting, and planning on using 300gr SMK's. I've combed these forums using every name I can think of for the cartridge, and really can't find very much info. I've read every thread I did find hoping to avoid being the noob that asks the same thing that's been asked and answered a million times already, but still haven't gotten what I'm looking for so here goes...

My primary reasons for choosing the 338W is 1) I already have a stripped 700 action with a .308 face waiting for a purpose in life. 2) Acoording to Cartridges of the World this seems to be suitable for my range/accuracy aspirations.

I'm thinking the bbl length should be somewhere in the 12"-16" range (I understand the SBR issues), and around a 1:7 twist.

I guess my two biggest questions are: Is this a suitable cartridge for the ranges I'd like to reach, or is something better suited for this (ie. 510W)? Am I in the ballpark on the bbl length and twist?

Any input is appreciated, just trying to use the action I have if possible. Thanks for any help you can provide.
