I am looking at building a new long range rig for using to 2000 yards, And it is going to be based on a Remingtom CDL in .338rum. I am looking at a 30 inch barrel,40moa rail, NF NXS 5.5-22x56 scope and a XLR industries chassis. My main question is will the .338rum feed ok from the AI .338LM mags, Or will i have to look at my 2nd option of using McMillan A5 stock with HS-Precision trigger guard and mags.
