Re: First long range riffle build need help
Just out of curiousity, what smith are you using out here? I was going to recommend you stick with the 300, but it looks like you are set on the Edge, if you are using the AI mag system I think you will be slightly disappointed, the magazine doesn't allow much of an OAL. I'm running the same setup in 338RUM & I'm not real sure I can even load the 300 bergers due to the increased length of the ogive area. McRees is offering a newer system that allows for a longer OAL but it requires modifying the stock & the action IIRC...
The 300 win mag will EASILY reach to 1000yds, will feed from the AI mags MUCH easier (less fiddling) & be easier on your shoulder.
With the increased length of the 338Edge I am really suggesting you do some OAL homework before going that route, you will be cramming the bullet SO FAR into the case you will lose any capacity edge you intend to gain over the Lapua or the RUM (which is minimal at very best).
