General rule if it's an 8 twist barrel, The 140's are pretty much standard. Prior to ditching
everything Creedmoor, I was working with 130 class bullets and got better results. But it
will depend on what your twist rate is, and 8 is usually what is used. If loading, my barrels
prefered the 140 RDF Noslers and the 130 Sierra HPBT's.
