My last two Lilja’s took .005 for Lapua. For Eley it took .002. That should give you a start.OK, so the headspace will be tight and will require shims to increase it slightly? This is my first time doing this just want to make sure I fully understand things.
There’s the right way and the way I would do it. I would use a socket and sand paperJust placed order for the 1.00" X 21" Lilja 22LR. Any suggestions on what to use to relieve the CZ 457 Varmint stock with? I have some sand paper. Is a socket good to do the sanding with? I free floated my Weatherby Vanguard a while back Seems I remember using a socket for that. I guess I need to seal it after sanding? Thanks!![]()
You can use fealer gauges if you remove the mag wellAny suggestions on a depth gauge that's not real expensive but, usable for this job? I've got a good Mitutoyo Digital caliper but, I don't know if it would work for this or not?
As I said, I have owned 6 CZ457’s 3 with Lilja’s, Never had an extraction issue.Well, it wont be a problem if, it will extract fired rounds or that would for sure, be a problem. I have a small section of fiberglass fishing rod I use to remove stuck live rounds.
Check out whidden gun works I believe it is. I paid the ridiculous price for a headspace gauge to Lilja and found a set for less than half price at whidden.Any suggestions on a depth gauge that's not real expensive but, usable for this job?

That's one way of determining what your headspace actually is. The best way to set headspace is with a go gauge. I set mine up so that the bolt closes as it should on a .043 gauge. This is a good middle of the road headspace and works really well with SK ammo.A you tube showed a guy measuring the action depth to bolt recess with the bolt guide out. Is that the best way?
Is that the one inch barrel also? From what I read, this barrel used a Manson reamer for the chamber. Some, they use a PTG reamer whatever that is.I have a 21 Lilja on one of my rifles for years, never once had extraction issues be it fired or live round. Lilja like many have there own proprietary chamber reamer, possibly they modified the reamer design this year for more rifling engagement ? Mine's about 5yrs old and has very minimal engraving. Excessive headspace can cause extraction issues, so measure best you can and keep headspace at a maximum 0f .043....042 even better.
21x .900 diameter. Lilja3 chamber, but it's a 5 yr old barrel. Maybe they changed reamer dimensions and shortened the chamber for more leade engagement, which seems to be the latest "accuracy craze" in the prs world. Mine barely engraves a few thousandth's, yet consistently shoots .150/.200 groups at 50yds with it's preferred lot of ammo.Is that the one inch barrel also?
