280 ackley 190 gr data

[7shooter]

Hey new here, just looking to see if anyone has tried the heavier bullets in a 280 Ai. Trying to find a good starting for load data.
thanks

I have good data for the 180 Bergers. My rifle is throated for the 180s and allows for quite a bit more case capacity as there is no bullet below the neck. 7828, retumbo, MRP are all good starting points. 7828 std cut is what I shoot the 180 at 2915 fps.

I would also like to hear some responses to this post. I am just starting load development for my 280 RCBS F-classer.
