Hornady load data 300 win mag older version
« on: August 29, 2022, 08:12:28 PM »
I am looking for someone with an older version of the Hornady book that might send me the 180 gr data.  The 11th edition no longer has imr 4350 data and I have a lot of that powder I would like to use before I break into my limited slower burning powders.  Thank you!

Hodgdon's online site list imr 4350 for the 300 win mag and 180 grain bullet.

I just looked in my Hornady 5th and 9th edition manuals and there isn’t any data using IMR4350.

Well it looks like I'll be using a different powder then.  Thank you for checking!

Nosler lists IMR 4350 which means it's still a valid powder to use. 70 grains max.
