But CZ really dropped the ball on the 457, because the 455 stuff doesn't fit, and it's a shame that Fedderson doesn't make a CZ barrel anymore. I just cringe at the thought of giving $500 for a Lilja but it's the only option right now. My 455 is so temp sensitive, our last NRL match it was cold and the CZ was helpless at 100, very disappointing. It's a 455 Varmint, 419 rail, 3-15 SWFA, Seekins rings and I was shooting cci sv. Nephews MK II with a Nikon p-223 shooting same ammo just stomped the CZ. And it wasn't the shooter, I shot both rifles the day before and the MK grilled the CZ. Long story short I should have dove in and got a Vudoo.
