Message: <blockquote data-quote="swampratt" data-source="post: 2703251" data-attributes="member: 15054">when I started reloading in 2009 I got 1 lb of varget  my brass was Winchester for my .308 the load was 44.5 grains for best accuracy with the 165game king with the funny looking hollow point. I could hit coke cans easily at 250 yards as could anyone shooting the gun,Groups at 100 were under 1 inch  for 3 shots.. usually about 3/4"I ran out of powder, so I got another pound,, I could not hit those cans at even 200 yards.groups were 1.5" at 100 I tried different brass I tried neck turning.. got into citric acid cleaning got another scale and compared the 2 side by side. I read and read on accuracy with brass prep.Decided to work up another ladder test and found with this newer lot the accuracy was best with 43 gr varget.Then I got more of that lot. Then I cut my barrel shorter and looked for even more accuracy so back to the drawing board I went.I have some 4350 made in 1994 and it is not even the same looking powder  today .. same goes for the IMR 4064 not the same stuff.Next time you are here I will show you some 4064 from 2009 and 2012. I should get some from 2015 and see what it looks like.You can also do a volume measure test.Scoop a few charges and weigh them, then scoop from a different lot and  weigh them.Sometimes you will find big swings in volume measured density of same brand powder with different lot numbers.But if you do not chances are those will shoot about the same</blockquote>
