I just got a 243 barrel on a trade, and I have been looking at my options for factory ammo since I don't reload.
The Light Mag ammo that hornady makes looks impressive by the numbers, but the box has warnings about what kind of gun it can be used in.
The 100grain bullets are factory rated at 3100fps. What kind of pressures are required to push a .243 bullet that fast? Is it within SAMMI specs? How about the the mechanical limits of a handi rifle?
