Faster twists almost never hurt if available.

My rebore 338-06 JES did 5 groove win rifling. I"ve not many complaints, but to do next time I"d probably just go top of the line barrel instead.

I shot a lot of 3 groove in 223....

Shoot a 5 groove in 308....

Thats all the data I have. I"m a bit convinced of the odd grooves myself...
