[QUOTE="BKM, post: 1841074, member: 71899"] Good info guys. This issue has been debated amongst the smokeless muzzle loader community as well. While most SML’s are 40’s & 45’s they are achieving velocities well over 3000 fps. With too fast of twist barrels the spin drift is terrible even if the bullet stays together and doesn’t spin the jacket off Many of the modern mzl bullets come with the aluminum tips. When shooters try to figure their Miller stability they measure the entire length of the bullet (tip included) and this skews their information. This was a very good video and explains the negatives of a bbl with too fast of twist very well. Think about it , if too much twist wasn’t a problem, barrel manufactures could simply make all barrels with a fast 6 twist and that would cover any bullet we choose to shoot. I apologize OP. Didn’t mean to derail ur post. [/QUOTE]
