CZ-527 from SSK

Riverguide — Sun, 08 May 2011 20:24:40 -0600

by: Riverguide

Description: A special request was made to have a muzzle break made to give the rifle a bit more of an attractive instead of the standard thread guard ring. The extra 2" of the muzzle break makes the rifle (in my opinion) look a bit less stubby, considering it originally had a longer barrel.

Speer: 125gr TNT vs 130gr Hot Cor

Fudmottin — Fri, 13 Mar 2009 18:24:14 -0600

by: Fudmottin

Description: Speer's 125gr TNT next to the 130gr Hot-Cor in .308 Calibre. Good for whispers? We shall see. The ogive is the same calibre on both. The frustum on the Hot-Cor with its slightly higher mass should yield better terminal ballistics for subsonic loads.
