Ok working on a bullpup with a suppressor that with be a sbr. 10"-11.5" barrel I am aware that a 1:9 twist is best for suppressor ammo. Question is do you thing it would also be ok to shoot bulk pack ammo out of it with the suppressor on. I found 10.5" barrels but the all seem to be 1:16 twist. Which I imagine will just cause key holing. So was going to buy a 1:9 twist and have it cut down to 11.5". Do you think that will provide me that happy medium were I can shoot both types of ammo in a supressor with out baffle strikes.

First off... WELCOME. Ruger factory barrels for the 10/22, Charger and 22/45 pistol are 1:16 RH twist. I have all three, and shoot all three suppressed with CCI Standard Velocity, and Winchester subsonic ammo. I see no keyhole, and no baffle strikes. Bulk ammo can be shot with no concern except it will be a little louder than standard, and subsonic, as most bulk ammo is high velocity. Use a 1:16 twist barrel with no worries.

Thanks even cut down to 11.5" my concern is just not getting that full spin. Trust me I rather just take my factory barrel and have it cut crowned and threaded. That is only $50 verses $150 on up. And you pretty much shoot a wide variety of ammo with that.

You could find a Charger take off barrel that is threaded. The new Charger barrels are factory threaded 10".I have an older Charger so I had mine threaded. I also had a 10/22 barrel threaded. Both barrel are extremely accurate. I wouldnt worry about finding a 1:9 twist barrel.

? Why do you need a barrel long enough for the bullet to make a complete revolution, before exiting the muzzle? Is that what you are worrying about? That has nothing to do with accuracy, or stability...

Higher twist rate barrels(1:9) are designed for heavier bullets. The 60 grain 22 rounds are suited for that twist. Most 22 ammo is around 40 gr and the 1:16 twist is better there.

Yes exactly to my understanding if it does not get a full spin. You can in turn get a baffle strike on the suppressor. I have a bunch of 36g and 40g (no not for sale hahaha). And would most likely buy 40g subsonic. Have you ever shot 60g out of your 1:16 twist. And are your results favorable. I think this bullpup is going to break the bank. There just a certain look I am going for with it and that requires a 11.5" barrel. Just want to do it right and once. Apprectaite the help and feedback.

That is incorrect. People have been shooting suppressed pistols for many years and have never encountered a baffle strike because the bullet didn't make a complete revolution before exiting the muzzle.

So in other words. Just cut the factory barrel to 11.5". And just stick to 36 and 40 grain ammo. And don't worry about it.
