This may be a hope and a prayer but what do you guys think about a 7mm rem mag past 1000 yards say to 1600 or so? I have lots of brass and love the high bc of the .284 bullets. I also have the dies for it already. I was planning on either a broughton 5c barrel or a bartlein finished at 32 inches. I am looking at a 1in9 twist witch will allow me to use the 180 bergers. Is this enough gun? Info will be greatly appreciated.
