"Accipere non casus-Virga Bis"
The other day I tested some newly arrived CCI Mini-Mag ammunition, along with some SK Rifle Match from three of my .22 rimfire rifles:
• CZ 457 MTR
• CZ 457 LUX
• Savage Mark II
Shooting was done at 45 Yards, with three sets of 5 rounds at each "spot"
The CZ 457 MTR seems to have a match chamber. When a round is chambered, the forward most driving band is engraved by the rifling:
This is supposed to be conducive to better accuracy.
