picked up this CZ 455 varmint evolution and out of the box with a Bushnell 2-7x rimfire AR scope and federal gold medal HV match ammo shot .62 " groups at 50 yards . this thing is soooooo smooth out of box.
IF you have not already, go to RimfireCentral. com and check out the CZ/Brno forum. They can help with reducing trigger pull weight (no matter where it is now), and a ton of other help.
I have a CZ 455 and it is indeed a great shooter....but it is not a match rifle by any means.
I shoot NRA 3 & 4 position indoor and outdoor and at 50 yards/meters I need to have performance in the ammo and rifle that is little more than the diameter of the bullet to shoot clean which is needed to to be in the winners circle.
