Starting loads for a .280 Rem with 154 gr Interbonds.

[Mills]

Here's the result. 154 grain Hornday Interbond using 58.5 grains of Reloader 22 with Norma Brass and CCIBR2 primers. This is a max load in the Hornady book so approach with caution. By the way, this was shot with a lightweight mountain rifle.
