I’m going to shoot it before I work on it. Rod, maybe CZ is listening to you!

Take care, Tom




I'll be happy to take the credit!!

When you pull it out of the action, check the rear tang area/bedding. Unlike, say, a SAKO, the CZ has a very small action tang portion of metal available to contact the wood. The bedding on mine was very poor indeed, with little contact even where there was tang metal to do it. A small dab of epoxy fixed the issue, but the action would probably have rocked side to side without it.

Part of the weight issue for mine is of course the heavy rings and scope I put on. The Burris scope I used is heavy. Tho my rifle demanded a lot of work, it has turned into a real favorite, as such guns often do for me.

Please let us know if your bolt will close on a round shoved up the pipe!

Today I sighted in a Leupold 1-4X Vari-X II scope on my new CZ 550 FS in 6.5 x 55 mm Swedish Mauser chambering. The very first group at 100 yards was 0.559 inches. I put up a fresh target and shot five consecutive three-shot groups at 100 yards. They measure 0.611, 1.422, 0.660, 1.141 and 1.198 inches. The average is 1.006 inches. The load is the Sierra 120 gr SPT, Winchester cases, Federal Match primers, and enough IMR-4895 to make 2650 fps, measured at 5 yards.

The largest of the five groups really shouldn't be counted. Before I shot it I removed the soft sandbag under the forend and rested the gun on a very hard sandbag. For the remaining groups, I replaced the soft sandbag. That one group is not only larger, but it moved significantly to the right as well. If I remove it, the average becomes 0.903 inch.

I'm certain that with a higher power scope I can shoot five groups that will average three quarters of a minute of angle or less. However, as a hunting gun, the 1-4X Leupold is just about perfect, and I'm satisfied with one MOA. That'll get the job done farther than I'm willing to shoot on game.

Take care, Tom
