That depends on how heavy a projectile you anticipate shooting. If you plan on shooting anything heavier than 123 grains, I strongly suggest a 1:8" twist. There's nothing a 1:9 can do that a 1:8 won't, but you can't say that in the reverse. Just go tight and don't sweat it.
If it's true that we are here to help others, then what exactly are the others here for?
