CZ-457 22rf works for me.

[NF1E]

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!
