Factory tapered barrel was cut to 16" recrowned and threaded for can. Stock was unmodified. Front support was a ruck rear was a Triad squeeze bag and all shots were fired from a bench at 25 yds 5 round groups except the one indicated as 10 round (was the best fired so I kept it).
Lilja barrel was fired same distance, position and support. Stock was pillar bedded as well as the first 1.5" of barrel. All groups were 10 round fired from two five round mags in under 1 min using a shot timer.
Ammo used (not shown is the CB shorts or the Rem bulk pak fired from the factory barrel)

16" CZ barrel
-CB shorts were just a bad idea lol 8" and I swear I saw one corkscrew out the barrel.
-American Eagle .455"
-Remington bulk pack .405"
-Aguilla SS .405"
-CCI Mini Mag .365"
-Remington HP .340" (10 round group)
21" Lilja
-Remington HP .410"
-CCI Mini Mag .310"
-Augilla SS .250"
-Fiocchi (40grn LRN) .250"
-American Eagle .215"
-Eley Target Rifle .210"
-Eley EPS .190" and .245" but I'm calling a flyer at top left that was 100% me so I went back and fired another 10 round group.
So whats it all mean? I have no idea as the Rem HP shot the best of the ammo fired from the factory barrel and was the worst from the Lilja. The AE was the worst out of the factory barrel but in the top three from the Lilja. I have NEVER spent $15.00 on a 50 round box of .22lr in my life but I have also never owned a high end rimfire so I was curious to try it. I may fire Eley from time to time but I was VERY happy that one of the cheapest ammo's tested fired only marginaly worse than the two most expensive match ammos.
Some quirks with the Lilja, the chamber is VERY tight and you realy have to use some effort to close the bolt also extraction wasnt as positive as with the factory barrel and I think the cuts may be a bit tight but I have not narrowed it down to that just yet. I dint have any failures to extract or eject but it wasnt as positive as the factory barrels were.
