HBB,
Thanks for the suggestion. I was thinking after trying some slower powders that maybe with the lighter bullet the gun would like a little faster burning powder. I'll give some H4350 a try.

Steve Timm turned me onto the 120 grain H4350 load when I built my .280AI.
I am running 61.0 grains (Near Max. so work up to it slowly) of H4350 with the 120 grain Nosler BT, Federal 215 primers, and fireformed RP brass. I get 3323 fps out of a 23 inch barrel and sub 1/2 inch groups.
The 120 Bt flat lays deer out.
