I was going to title this one, "What is the best short action, precision cartridge for a build", but...then figured it would go on to at least until Christmas and 500 replies. . And...with that "BEST" added it would probably start a few keyboard, strong discussions between the opinionated members here before it was done. I am thinking either a 6mm BRA, or a 6.5 Grendel, but I am not certain about the Grendel?? The latest that I have been told is the 6mm Creedmor is something people are starting to sway towards, however....by Creedmor is a tough one to swallow!! This probably is going to be a "one-piece-at-a-time build due to the cost involved; budget around $3000 or maybe a little less without the glass. I want to do something with a heavy barrel, short action rifle, something that would be a pleasure to shoot for a day at the range. The furthest range that we have is 300 yards so that is a consideration when asking for member's opinion.
