Whats the Most you can bore out a blaster before you need to put a sleeve in it? Also is it more susceptible to blowing up bored out 80 over? What is the main cause for for a blaster blowing up???


Thanks!

 

since no one answered, ill give my 2 cents, my blaster is bored to a 260 and i dont have a sleeve in it, but i dont know how much higher till you need a sleeve if that helps any...and i dont think its more to blow up easier if its done right
