First, DISCLAIMER:
These are loads I worked up. Some was from data on different bullets/cartridges, some from information I found online, some was figured on my own. They worked for me, I can't guarantee they will for you. So use with caution, if you do.

Mag primers a little higher velocity, as in average 880fps vs. 867 for standard. Which isn't enough to worry about. Would the ignition characteristics mean better accuracy at longer range? Might find out later.
On all the cases were clean enough to indicate high enough pressure for the cases to properly seal, no flat primers indicating high pressure. So I think I'm safe in upping the charge a touch. I'd like to get these to about 1000fps so they'd be in the envelope for expansion*.
*Hornady says these should expand down to 900fps, so want to be above that.

I'm not a reloader. Not a marksman, either. But I like that stuff..
But I'm not sure I would know How to do that Cautiously. Close my eyes when I pull the trigger?
Why I have that disclaimer: I'm just working these loads up from comparisons to other cartridges, thinking, and making that sometimes dangerous statement "Yeah, this should work."
Don't close eyes but do use good eye protection, and if I had a suitable stand I'd have the rifle locked in it for that first couple of shots so I could examine the brass before setting off that X-thousand PSI deflagration while I'm holding it.
I'd imagine some ballistics specialists/engineers are holding their heads and saying something like "No, don't do it that way!" as they read some of my stuff.
