trying 3 new loads, are they safe?

Just a suggestion...segregate your brass to like makers...ie, all Winchester, or Federal, etc.
I had incredible success by doing this, and even went to the extreme of weighing each case. Accuracy remained consistent throughout all my testing over the years by following this technique. Though finding a good quality maker is difficult. I use nickel plated Federal 30-06 in my 1903/1922 sporter, and Federal Brass in the Garand, Winchester in the P-17 and R-P in the M1903 milspecs.
