I'm looking to get out to a mile and could use some thoughts and advice. I have a Remington/Magpul 6.5 Creedbun, 20" barrel, that shoots pretty well, first photo and second photo is today's target, most of the wides are me, not the rifle., It appears that this is a .5 moa rifle if I do my part I wasnt feeling great this am but the range trip helped. Its one of the new Remingtons. I found an older one (I think) in stainless with the 5R barrel, 26 " barrel. 3rd photo below. Im wondering if the 6" longer barrel on the older rifle will improve accuracy at distance over the shorter barrel? Its also been blueprinted and the barrel set back whatever that means. Timeny trigger like in the Magpul one. If enough to go to a mile, or should I look to a different caliber and spending a lot more money in both rifle and ammo...which I really dont want to do at this point. I have one of the stainless ones in 223 though and its a real tack driver with the right ammo.
