And has the LIJAA tightened your groups much. My sporter, with Eley Match is as near perfection as one would would wish for, but there again the pursuit of perfection is endless!
Ahh - The pursuit of perfection.

To be honest I've always been a little disappointed with the accuracy of .22 rimfire when compared with centrefire. Don't get me wrong, I'm not knocking the .22lr, it's an excellent tool and tremendous fun at an affordable price, I've used it in many forms for over fifty years and for some jobs it just can't be beaten such as various precision pistol events like rapid fire, free pistol etc. where benchrest accuracy comes second to technique. Also as a rabbit and small pest harvester with subsonic ammunition and a moderator it's second to none.
Yes, I can shoot a rabbit at 100 yards with a .22lr but with my 6mmbr I could decide in which eye to shoot it, why can't I do the same with a .22? The answer is of course, the ammunition. It's a massed produced 130 year old design and long ago reached it's practical point of perfection. General perceived wisdom is that the best match ammunition was produced in the early to mid 90's and certain batches of that era are much sought after.
With a centrefire you can tune the load to suit your rifle/barrel, with a rimfire it's not so easy, you can chop and change your ammunition to suit your barrel or go the barrel tuner route.
Serious match rifle shooters can arrange to take their rifle to Eley and, under carefully controlled conditions, rifle clamped in a solid rest in a tunnel range can try many different batches of the best match ammunition (not cheap at more than £20/100)
The variation in the various batches is, quite frankly amazing, remember this is from rifles costing £2,3,4k.
So - Is the Lilja barrel more accurate? Yes, marginally. Was it cost effective? - No not really. Do I regret buying it? - No not at all - Trying to wring the best possible result out of my rifles is just another part of the sport I enjoy. If I was just after controlling the rabbits I'd be quite happy with my semi-auto, it does the job very well.
This is 5 rounds with the Lilja barrel through the same hole at 25 yards, the new round won't fall through the same hole:

This is 5 rounds at 200 yards with my 6mmbr - can be covered with a pound coin:

I'd like to say, yes, It'll shoot sub 1" groups very time - Unfortunately it's only sometimes.
