Mickey-I am not for cetain what twist Wby is using in their 340's--10 I would guess.

I've used 10's on all of my tubes and they will shoot the 300 quite well--I don't feel it is a twist problem-perhaps-but most likely not.

Now for opinions on brakes--not for me-no thanks I want to be no where near those things.....IMO a 340 if built properly (at least the way I like them) their bump is not so much to be caustic--now brakes their is something that is caustic.

Just my thoughts and opinions.
