Maybe I'll give pillar bedding a shot first.. I'm still working on finding decent 22 LR. Thanks for the thoughts!
Like the others have already suggested. There are a few things you can do to your CZ 455 before you sink a huge amount of money into a Lilja barrel.
This is what I did to my 455s in 22LR to make them shoot MOA at 50 yards. Others might have done more or less, a lot of this have been discussed in the past.
1) check torque values on the action and the barrel attachment screws
2) the barrel should be freefloated from the factory with a plenty of clearance
3) lighten up the trigger to 2.0 - 2.5lbs, take out creep. You can buy yo dave or do a "poor man's trigger job" as per RFC
4) shoot with
good target ammo and see what the rifle can do (I would suggest sk standard plus or better; try few reputable brands like SK/Lapua/RWS/Elley).
5) check crown and fix it with lapping compound if required
5) ensure that the bolt is not shaving your bullets while travelling over the next round seated in the magazine (just cycle 5 rounds through without firing and check with magnifying glass for scrapes in the lead on the "last" 4 rounds)
5) pillar and glass bed the action and the first 1.5-3 inches of the barrel.
If the rifle still doesn't shoot consistently close to 0.5 in at 50 yd, you might have done a bad bedding job (I know I did when I was learning....), or you might have a bad barrel assuming you optics/set up is all good and your bench shooting technique is good and rifle is clean.
Good luck
Kody
ps: If nothing else works just buy a 452
