280ai load data?

[hawk-i]

Does anyone have data showing max load for 280AI and Hornady 154 sst's with H4831sc and IMR7977?

My 9th edition Hornady does show 280AI and hodgdon load data doesn't show 154sst.

Use 150gr data. Hornady has that bullet in with the other 150gr bullets.

Will shyt, I went and bought the Hornady 10th edition because it said it listed new powders including IMR 7977.
On the IMR 7977 container it lists the 280AI as being a suitable cartridge for this powder.
10th edition doesn't even list it with their 280AI load data.

Way to go Hornady! Lol

Hawk-i..........A good rule of thumb for any AI case is to start at the upper end of load data for the original case and work up. Most AI cases will max out about 5-7% over book max for the parent cartridge.

My Hogdon book only lists 150 gr. BAR TSX with IMR7977 59.6 start-63.5 max and max load is compressed
150 gr. SFT SCIR with IMR7977 58.8 start-62.2 max compressed

Use the hodgdon online database. It's a very useful tool.
