F class load development

[dthomas]

I am just starting load development on a new barrel for my f class rifle with a 30" barrel. I am using h 4350 with cci br2 primer Peterson brass and berger 184 hybrid in a straight 284 win. What speeds are people running these at? It looks like there's a node in the lower 2700's and there may be one at a full 1grain powder charge lower but I think it's going to be to slow. Should I be testing closer to 2800? Also how wide are the seating depth nodes for this bullet? Initial testing shows to be a narrow node.

I shoot them 2800+.

When I was shooting the 184’s in a 32” barrel the node ended being around 2,770. With 2” shorter barrel I would think low 2,700’s would be spot on. I test seating depth in .003 increments and can normally find 2-3 increments wide for a node.
