I have been using BIB bullets in my 22-250 that has a 1-14 twist for about a year now.  I have shot 19   5 shot groups @ 100yds under 1/4",  I average .45".  I have a heavy 26" Lilja barrel and use 34gr of 2520.  I can not shoot like this with any other bullets.  Does anyone else have success with them?  I think they are the best out there.
