I'm switching from large cci primers to magnum 215. It's for a 300 win mag and I was wondering how far back I should back my load off when doing so? I'm running 208 with .010 jump and 76.8 of h1000. Should I just do a quick load development with them and start over? Thanks for your advice.

The cci I was using were large primers and switching to magnums. I didn't put that in my original post. Sorry for the confusion.

I wouldn't ditch your load....back it off 10% and work it back up until you achieve the accuracy you are after
