Mag Blends Question

[campcreekfarm]

First off I would like to say that I do more reading on here than I do posting.  So if my question has been asked before I apologize.  But I had a box of Mag Blends ( 3 1/2) that I have had for about 3 or 4 years that I finally decided to pattern yesterday and they did real well and I was happy.  And I am thinking about buying some more for my trip to Missouri next week.  However, I thought I had read on here that they had changed and there were bad lot numbers to look out for and not get.  Can someone please give me some advice on what to look out for and are the new ones just not as good.  Thanks.

Also has there been any changes with the 3" Mag Blends that I should look out for?

I think a lot of Hevi-13 loads the last couple of years haven't been as good as the earlier batches.  All the magblends that I have aren't very good.  And the same goes for the #7 loads.
