Beat me to it, agreed.It can be detrimental to accuracy but as with many things its not written in stone.
If you have a specific reason for needing suppression, do one, if it's just because I got this cool new can and I want to thread everything, still do one, I would hold off on doing all at once.
If one of them is a lights out shooter, I wouldn't touch it.
Do some searching through these threads and you will see many opinions on threading rimfire barrels.
Saying it will destroy accuracy is an extreme statement, but it sure won't help. If you're trying to milk every ounce of accuracy from a barrel I wouldn't thread but since you want to shoot suppressed I doubt you're concerned with that level of accuracy as anything you hang on a barrel will effect point of aim and accuracy most of the time in a negative way. With the exception of a tuner.I have a couple kimber and cooper 22lr, they all shoot great but I would like to have them threaded for my suppresor. Is there any downside to having that done? I’ve heard it will destroy the accuracy.
Yes. Adding my TBAC ultra 9 has only improved accuracy for my guns. Be it controlling muzzle gas, flinch etc etc whatever argument one wants to make. I’ve seen better results. But we’re talking match grade guns and heavy barrels. If the gun shoots 1 moa or worse I say most won’t notice a differenceSo your saying it could improve accuracy as well, if using the tuning fork argument.
Adding a suppressor, or any weight on the muzzle (or anywhere on the barrel) is what effects harmonics, so I suppose one could say that removing a few grams from the muzzle area by threading can effect harmonics. However that is not the main reason threading a rimfire barrel can effect accuracy.Please explain how threading a barrel will affect the accuracy of a rifle.
Anschutz NA counter bores their threaded barrels. I do know of a few where the counter bore caused some accuracy issues / inconsistency. Again these rimfire bullets are very sensitive and that includes the precursor gases. Maybe a well designed suppressor will help by getting the gasses stable before the bullet gets there.I've seen/ heard of people counter boring the muzzle to behind the threaded section to give it a recessed crown essentially to bring accuracy back/ void any problems
I think tuners are bullshit. Especially since Erik Cortina pimps them so hard. He's a joke. I used to have to deal with his BS over on LRH. He's one of those "only full-length size your brass" pushers. When fact is, neck-sizing belted cases is actually significantly better for the brass longevity and can improve accuracy.My understanding is that a quality barrel blank that's been bored out and rifled with quality equipment and processes, and with the muzzle end threaded with quality equipment and processes, that this isn't a concern.
What I find bizarre is that people claim that threading will bell/flare out the muzzle and degrade accuracy, but do it anyways to add a tuner. Those two actions seem to be at odds with each other.
