[QUOTE="new2mud, post: 2050664, member: 24831"] 300 BO is optimized for short barrels, with nearly complete powder burn in first 9” or so. Very little to be gained with longer barrels in this cartridge, so you are good there. If looking for something a little different with excellent BC and long-range target capability while still able to take deer out to 400 or so with very little recoil, take a look at the 6mm ARC that Hornady recently standardized. I helped a friend build one in 22” and wow that thing has potential. Supersonic past 1000yds and barely more recoil than 223. You will need barrel, 6.5 Grendel type 2 bolt, and Grendel mags. Standard AR15 platform—does not require larger AR-10 platform. [/QUOTE]
