I loaded up a bunch of test loads (9) for my 338 Win Mag Tikka T3 Lite the other day, and they all fired fine with no signs of over pressure. All 9 shots went into a 1.5" group. (three different powders, loaded in one grain increments) But when I went back to load up some more similar loads I discovered that I had used Federal 210M instead of the Barnes recommended Fed 215M. Being new to reloading I don't know what to do at this point. If I load up some more of these loads using the "wrong" primer and they chrony and group well, I can't see a reason not to hunt with them.
What should I do? Go back to the 210M or go with the 215M and re-pressure test?
Thanks in advance,
