Any decent rifle with a quality barrel and adequate caliber should be adequate to 300 yds. Past that distance shooting gets to be somewhat of an artform and sensitive of technique, etc..Past that we must worry about trajectory, wind, placement, and bullet energy, to make a clean kill.

I have a $600 308 Savage that is positively deadly out to 400yds.It all depends on how the barrel and bullet work to gether.I prefer a combination of relatively no wind, a laser range rinder and a Swarorski TDS scope for the long stuff.Works for me!

I think the Barnes MRX bullet is going to be a great long range bullet with the lead in the tail for stability and the X bullet front. Time will tell!!
