The trigger spring has been changed, and 22" Whistlepig aka Acculite Acculite GunBarrels for Ruger 10/22 | WhistlePig GunBarrel Co
The original barrel shot good, but the Whistlepig took it to another level.

5 shots at 50yds Eley Target

Did you order the match chamber or which one?

Yes I ordered match chamber
The weight reduction made it feel totally different.

No kidding. If I thought I could shoot that tight I'd order one right away. Nice job OP.

Thanks

I don't usually take "culled" results seriously.

Only the ones I post

It has to have a few rounds through it and then the groups shrink. I have to remember to change my hold sine it is so much lighter now

Any shims ? What’s your headspace?

no shims, I've not checked the headspace. I followed Louis' instructions including the break in procedure and extremely pleased with the results. The is my second barrel from Louis, and won't be my last. The other is a 10/22 and it shoots great too. If I could change anything about his barrels, would be putting his name on them and perhaps "match" chamber when applicable.

Do all your targets look that good? If so, you got one heck of winner. I replaced the stock barrel on my 455 varmint with a WhistlePig and the results were the same as the stock barrel, which was not very good (about 1" at 50 yards with target ammo). It did make the rifle feel a lot different but no improvement in the groups. It may be an issue with my rifle and not the barrel.

I have two WhistlePig barrels and they both shoot great. I'm assuming you've tried different ammo, the barrel on my 457 isn't what I'd consider to be an ammo snob, but it does shoor RWS Match, Eley Club & Target better than some of the others I've tried. If you've not reached out to Louis, I'd also recommend giving that a try. I've only spoken to him once but was impressed.
