I have a Rem 722 SA custom with a Schneider polygonal barrel. Every once in a while folks ask how it (or more specifically the polygonal rifled barrel) shoots. Here's todays re-zero results, I needed a re-zero after putting on those scope levels I got from Mid-South. 243 Win, Lapua brass, 105 Lapua bullet First "real" group (in the center) is 4th through 6th shots after cleaning the barrel, 1st through 3rd are at the top of the target (I needed some scope adjustment after playing with the bases and scope rotation). .314" center-to-center Here the second "real" group, 243 Win lapua brass, Hornady 105 A-Max. .264" center-to-center All-in-all I'm pleased with the barrel and the rifle, I've had this rifle for better than a year now and it's helped me kill a few deer. A little more about the rifle. It's a Rem 722 SA with a Rem 700 bolt, Schneider polygonal rifled barrel, H-S floorplate with detachable mag(s) (a 5 round and a spare). Badger base (clip slotted), Badger rings, McMillan HTG/A1 stock, Nightforce 5.5 x 22 NXS scope and a brand new B-Square bubble level.
