So, have you shot them? Just curious, do you have a preference for the chassis or stock when shooting prone or off the bench?
What kind of ammo are you shooting? My factory barrel would only seem to shoot SK/ Lapua.
Start at 15 in/lb going up 5 in/lb up to 25 or 30. Shoot a bunch of groups at each 5 in/lb interval and let the rifle tell you what it likes best. I've read that 20 in/lb is what a lot of these rifles like
I shot my MTR yesterday with Center X, 7-5 shot groups that averaged .420" @ 50 yds. The rifle has about 400 rounds thru it so far, I was hoping for a little better, I do need to make adjustments to my rest and rear bag to fit the stock better. Hopefully with a few hundred more rounds it will improve some. Trigger is 10oz. used a 24X scope. Head space at .044" Thoughts ?
Don't know how much difference it'd make, but I like headspace of .043" for SK/Lapua ammo. Have you shot any Eley through it to compare groups to what you normally get with SK/Lapua?
Yes id rather have.042 for Eley, the rifle shows signs of wanting to shoot well, sometimes get 3 or 4 nearly thru same hole with 1 or 2 fliers.....hopefully more shooting will improve things a bit...thanks
Go to Lilja Barrel website they have a good video how its measured. I believe its found as a link on the CZ455 and CZ457 page.
Here the link for measuring headspace

Thanks, order placed, depending on how the bolt feels, the shims may not be a fix, but will temporarily allow me to test different head spaces. That's a good thang!
i was interested in a Lithgow as well until i read about all the feeding issues, i really wanted one for a minute
Yes thats correct, slows wear down, any type of grease or moly grease is what I use....just needs a little
I think I’m in love.
How much?
From what i can find right now, it looks like it will be priced around 1100€ in Europe, so expect something like 1200$.
I can't see it making it at the same cost as a Manners stocked rifle.... Perhaps the stock is a higher quality than it appears in the photos. At the same cost as the AT Varmint yea....that would be great.
Just my .02.....
Just my .02.....
For those of you running suppressed, are your cans shouldering up the barrel all the way?
Looking at the TBAC .22 LR thread specs, it calls for 0.400 overall thread length.
I have two new CZ457 16" Varmint Precision Trainers, both are measuring 0.458 - 0.457 overall thread length. Running SilcenerCo Sparrow 22's, I have about a 0.05 gap between the back of the can and the barrel shoulder. The Sparrows come with a 0.25 spacer to run on the longer 0.60 standard centerfire threads, but that 0.25 spacer seems way excessive (and ugly) to close the 0.05 gap.
Here is what the gap looks like. The can is snugged up on the threads tight. Both 457's have a similar gap, and I've tried it with differnt cans. Run it? Shim it?
