Good to Know. My 8 twist like a 140 AB on top of a heap of 7828SSC. But I just competed a 9 twist.
Still shooting this load and with good results. Here in Michigan, Ramshot Magnum powder is available and only $26-27/lb, considerably cheaper than most powders. Magnum is a fine ball powder much like H380, easy to meter and it burns very cool, unlike RL33.
I'm going to try this working with 123gr ELD Hornadys, should work as this gun shoots 130's equally well. The 1-9 twist will not shoot boat tails, but flat base Core Lokt 140's are decent however not as accurate as the 120/130's.
Forgot to mention that the rifle is also bedded.
