I am interested in a good recipe for the Hornady Interbond 154grn bullet in a 280 cal. It will be shot in a Ruger M77 sporter with a 22" , 9.5" rh twist barrel. I would appreciate any feedback. Thanks.
I don't load for the .280, but with it's similarities to the .270 I would suggest trying H4831, RL-19, or RL-22 for powders.
H4831 and RL-22 are my favorites for 150gr in the .270 (which specs out almost identical ballistics-wise to the 154gr in the .280).
I suspect you would get good results with either powder...both of which are on the Hornady manual pages that rcairflr posted up for ya.
