[QUOTE="CCAguns, post: 3087323, member: 15399"] 4350 might be a little fast for the 280AI with 140gr bullets. I got very good accuracy using H4831 while building a load for my 280AI with 140gr NBTs. Started getting slight pressure signs at 64gr - nothing before that. Note that Hodgdon lists max at 62gr. Good accuracy node at 61gr with velocities running 3050fps from my 21" barrel. Probably add 35fps for every inch of barrel longer. Started at 58.5gr H4831. [/QUOTE]
