CZ-457 22rf works for me.

Shot a five targets this morning at 100 yds. Couldn't resist a chance with no wind in Mark's Hollow. Rifle is a CZ-457 with Timney 10 0z trigger, Lilja 20" SS barrel,single load adapter, S-7 bipod and Sightron SIIISS 10-50x60mm. She prefers the X-ACT at 100 yds even though it's a little slower. Whatta Hobby!

Nice shooting! Love my two CZ 452's - a Lux in 22LR and an American in .17 HMR.

Very nice groups! I gotta get me a CZ rifle. I have a CZ P-10F pistol that shoots like a laser.

I bought a LH 457 Varmint a couple months ago. Fantastic rifle! I still need to take the barrel off of it and thread it for my tuner and suppressor to go on it. I installed a different trigger spring and a stainless steel trigger pin, the trigger is now set at 10 ounces. Installed an Area 419 30moa scope rail, and an Arken EP5 5-25x56 scope.
So far this rifle really likes Wolf match ammo. I want to try some SK ammo but just haven't bought any yet.
Just for giggles, I put one of those Limbsaver rubber barrel tuners on it. These things actually work!

Without the tuner on the barrel, it shot like this at 50 yards- around 3/4"

With the tuner, at 50 yards - around 3/8" and even better if I didn't screw the second group up with one shot.
