Not a .243, but a .270
Some years back I pulled a good mule deer tag, and went looking for a premium factory load to use for possible long, 400+ yard shots.
I purchased a couple of boxes of well know and respected factory $40+ fodder with premium bullets, and 2 boxes of $13 Federal �blue box� stuff to use getting on paper and practicing off hand shooting.
Long story short, the high dollar stuff was disappointing, but the �cheap� Federal blue box stuff produced 400 yard group after group at 2 inches or less..
The buck stepped out at a lasered 403 yards, and I put one through his heart and out the other side.
Federal blue box is now my deer/antelope load. .
