The old rule of thumb was around 74gr. 4350. I used that same load with 350gr. Barnes .049 jackets, years ago. Similar loads should work with Woodleighs.
: As with any loads at or near maximun - one must reduce 5% and work as pressure indicates.
: What is safe in one rifle, may not be in another.
: Seating depth and chamber/throat shape dictate presusr changes between rifles.
