After reading all the threads where the lot numbers of Hevi13 were mentioned, it got me thinking about something that perplexed me this year.
Last year, with my 3" 870, 28" barrel, Indian Creek .665 choke, and 3" Win Sup HV #5's, I shot 116 in 10" at 40 Yards, and was impressed. This year, I got 90 in 10" at 40 Yards, with the same setup. 90 is still OK, but I lost 26 pellets, or 22.4%.
I remembered that I had bought a pile of the 3" Win Sup HV #5's, and decided to check the lot numbers. Out of 7 unopened 10 shell boxes, 6 boxes are the same lot number, and 1 box is a different lot number. Plus I have a half a box of who knows what lot number, because I had opened 2 boxes of the HV #5's, and I didn't keep the boxes. Out of 9 original boxes, I have 7 1/2 boxes left, and I don't know which lot number shot 116 with #5's last year.
Dang ammo companies!!!
