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.
