Thanks for the post RT2506 and johnnyk
johnnyk - I think you're 22" barrel is giving good velocity, based on the hodgdon's reloading data which shows 2960fps for a 120gr bullet with 46.5gr H4350. Are you seeing pressure signs at this velocity?
Its among the top performers with no other (hodgdon's) powders exceeding 3000fps.
Likewise, the fastest powder that Alliant shows for a 120gr bullet, is RL19 at 2950fps. RL15 and RL17 are a bit slower.
I don't have my Nosler manual handy - maybe it shows higher velocities than you're getting?
Has anyone else got a 24" or longer barrel, and does it really increase the velocity much? Maybe there is more effect with heavier bullets like 140's??
