Load data for 338 Norma Mag.

[Larry]

I have a Savage 110 in 338 Norma Mag. and having no luck in finding load data.
I would like to use IMR 4350 with 250 and 300gr bullets. This is not for hunting, but for LONG RANGE COMPETITION . No interest in Max or LOADS NOTED DANGEROUS , but good accurate load only.
Thank you for your help

As the Lapua burn rate indicates in this case capacity range I have found the 4350's burn rate very similar to Norma URP. Norma gives a load with URP for the 250 grain class bullets.

Can't be much help on the 300 grain bullets as I would expect the 4831's to RL22/MRP class powders best suited for this bullet weight. A Quickload run would help a lot, but would expect 4350 be low on case fill for the 300gr..
