338 Lapua Loads Using Reloader 22

I can't help you on load data, but I'm curious why you went with a faster powder like RL22? RL25 is much better suited to that cartridge.
 
Get what you can brother, finding gun powder is still a bitch, my favorite is H1000 but very hard to find. So I am purchasing anything that is on the shelf that can be used in the 338 Lapua, I just have not come across any data yet for a 285gr bullet yet everything is 250gr to 300gr. So I thought I would drop the dime here to see if anyone had any data yet so that I would not have to start a baseline workup for it.
 
I am using 85.7/RL-22 with Hornady 285 for 2755 out of my Salvage BA-110. Tried a few other powders and noticed Hornady manual had data for RL-22, which I have a "lot" of. Shoots very well, hope this helps and if you need more data let me know and can dig the book out.
