My 22 shoots 1/2" groups at 50 yards/meters all day! Really? Prove it!

Cool, you've probably got one after they switched to the Bentz chamber. I've got a prototype Lilja coming my way from a group buy set up on Rimfire Central. It's back to the EPS Match chamber, cone breech for indexing (glue in if indexed, but has notches for barrel screws if you don't want to glue or index) and has a shim kit so you can set headspace properly to the action. A gunsmith in New York, who customizes many CZs, found that accuracy in the Liljas dropped off a notch after changing to the Bentz Chamber, among other issues with the drop-in platform. He set up this group buy to address all of that, 23 of us went in on it, the results might convince Lilja to switch production to this design. One buyer has posted initial test results and it is looking very, very, promising.

Mine is an older one that was one of the earlier/earliest batches that made it to Canada. It is not the EPS chamber, but boy oh boy does she shoot. It is a pinned (screwed) barrel. Headspacing was not an issue with mine, as the difference in tanon length between this one and the factory was < 0.001" I guess having an early 455 ('B' serial number in the early years of the 455's), and and early Lilja spared me from the troubles that the later versions of both experienced.

By gunsmith from NY, you must be referring to djdilliodon? If so, he's a great guy, who I've chatted with a number of times over the years. May I ask how much a barrel in the group buy is going to cost you?

Thanks,
Cal.
 
Yessir, Don is the man. Headspace is a crapshoot with any random 455, I have a "B" that was loose at 0.048", and two "C"s that I've measured were good at 0.0445" and 0.0425". For sure the Bentz Liljas can shoot well, Carson tells me 0.3's and 0.4's are typical groups at 50 yards with them in the Varmint contour, warrantied to shoot under 1/2". The difference with EPS chamber is splitting hairs, 0.2's and 0.3's for groupings, or better if you find a good lot and/or install a tuner.

The group buy barrel was $400 USD shipped, which equaled $550.99 Cdn at the days exchange rate. I'm going through Prophet River for import, and will pay them an additional $50 import fee, shipping to me from them, and tax on that sale. Ballpark another $90 or so. Alberta Tactical (Lilja Importer) quoted me $725 Cdn + tax and shipping to me to bring it in, would have been faster, but I save at least $200 going through Prophet River.
 
Time to mark a Lux on the list.

Rifle: CZ 452 Lux
Scope: Fixed 4x Leupold
Ammunition: Eley Edge

Group sizes: .500, .466, .294, .490, .411

Smallest group 0.294"
Group average: 0.432"

Still needs break in with under 400 rounds through it. Weight 6 lbs 15 oz, trigger over 3 lbs.

That's incredible shooting with a 4X scope and a relatively heavy 3 lbs trigger.
It's hard not to note a fair bit of space between outer shots, enough to put a .22 hole between them and still have room to spare between each one.

G man, his rifle weighs almost 7 lbs, trigger around 3. Yep, a few recent posts here show some questionable groups. The requirement should really be to show calipers on the largest group.

I added you to the successful list.
 
It just follows that if the largest group is shown under 1/2", the target is very likely an honest success. Sometimes we might see something with many high 0.4's and the eyebrows may be raised a little, but I don't care enough to spoil anyone's day if it is their prerogative to fudge it a little just to make the list. If "cheating" makes ya happy, have at it :)
 
I had a CIL Anschutz Model 310 last year but sold it and soon wished I hadn't. A few weeks ago I found one at a gun show for a good price. It was made in 1965. I refinished the stock and put a new scope on it. For a lightweight sporter, it can shoot.






Groups from left to right: 0.421, 0.403, 0.301, 0.480, 0.496"
Average group size: 0.420"
Rifle: CIL Anschutz Model 310
Scope: Hawke Vantage 6-24
Ammo: SK Standard Plus
Distance: 57 yards
 
Great job those older 64 actions work awesome. If you don't mind Glenn what did the 310 cost you? You can pm me if you don't want to disclose.
How's the trigger?
 
The Eley edge bullets measure .224" I wouldn't get too worried about it.

What does the bullet measure after passing through the bore of your rifle? ;)

I used 0.195" on my last successful attempt, after averaging the size of the smudges left behind on the paper.

Either way, as per the thread starter.....

I'm fine if you subtract .224" from your outside to outside measurement.
 
If you actually measure the holes in the paper you will find horseman2 is correct. I've measured hundreds of groups have yet to see ANY that are .220.
I don't want to belabour a point. But should anyone be quibbling about 0.005" (the difference between 0.220 and 0.215")? That's five one-thousands of an inch. It's not a lot to argue about.

Many of this thread's successful challenge shooters have used .22" and .222" and even .224". To invalidate all of them would be a thankless proposition, one that would seem to fly in the face of the spirit of the thread, which is to encourage consistent shooting and a way to distinguish the keyboard shooters who claim things like "My 22 shoots 1/2" at 50 yards all day long" from those who can actually do it five times in a row on the same target.
