    Bolt Shims

    Me and another member of our gun club have a CZ Varmint MTR .22 cal. He installed bolt shims in his and hopes it will improved the guns accuracy. Are bolt shims really necessary in a MTR since it has a match grade action to begin with?

    CZ 457 Varmint MTR Action Screws

    Shooting a CZ 457 Varmint MTR with Norma Tac 22 ammo. I shot a 5 round group at each target at 50 yards. Using a Wheeler F.A.T wrench. Starting with 15 inch/pounds with 2.5 inch/pounds increments to 30 inch/pounds, I adjusted the action screws. It seems as though the 15 inch/pounds setting shot...

    Bench Rest Shooting IBS 50 YARD

    I am shooting a CZ 457 Varmint MTR with a Weaver Classic V 4-16X using CCI .22lr SV. It is sighted in at 50 yards and very accurate however for some reason I will start shooting in the 2 o'clock area on IBS Rimfire 50 yard targets. Am I doing something wrong squeezing the trigger or what...

    .22 Ammo Flyers

    You are shooting a 5 shot group from a rifle rest. Everything is great. Suddenly there is a flyer. Outside of shooters error, what would cause this? I understand that it's the ammo, but my question is why? What causes one round to not shoot consistent with the others?

    This is my first CZ I've owned. The only thing I did, after about 500 rounds, was adjust the factory trigger down to about 1.5 lbs.

    CZ 457 Varmint MTR

    A couple weeks ago I got a CZ 457 Varmint MTR and mounted a Weaver Classic V-Series 4-16X with Warne rings. Recently the weather finally broke and got a few hours at the range. After sighting in, I started breaking in the barrel with Eley Standard Velocity ammo. Here a picture of one of the...
