there a re three thinsg when talking about a tailed beast bomb
1 - the attack itself is fast and the ball is shot with considerable speed , dont forget the size of the ball which accounts for quite some distance and added to that the travelling speed
2 - the initial blast (i.e epicentre is quite big ex - rasenshuriken epicentre shown in the pain arc when one of the pains got stuck in the middle
3 - the last thing is the range of the blast which is quite big
so talking about avoiding the beast ball
- first he/she has to move out of the way of the inital blast epicentre ( or initial blast range) and then he/she has to keep going inorder to completely avoid the blast
the alternate way is for shinobi with large scale justu to try to redirect the trajectory
ex - hashirama , naruto firing a tbb to the under side of oncoming tbb ,
