[QUOTE="swampratt, post: 3863802, member: 15054"] Read this. [URL unfurl="true"]https://www.okshooters.com/threads/3-different-lot-numbers-of-varget-target.210791/[/URL] And are you saying you loaded some of the ammo you shot way back in 2012 and some was loaded in 2018? I recently showed a member on some old loaded ammo how a bullet can "weld" itself to the case neck after a period of time sitting. Take some old ammo you reloaded and stick it in the press and seat the bullet just a few thousandths shorter. You may hear a POP when you break the weld. If you do that ammo will NOT shoot the same as some ammo you made last night. Now if it easily seats deeper with no POP sound you done good and it will probably shoot the same if lot numbers are the same. I had some .223 that was less than 2 years old shooting from a bolt gun. H4895 powder and 55 V max. I noticed one round kicked much harder and had a pierced primer and then another round kicked pretty hard no punctured primer. I took those home and did the seating test and they all had a POP to them. I took them apart and all had exactly 26 gr of powder. I trickle on a beam scale. That was the first time it happened to me. CCI 450 primers were used. [/QUOTE]
