I posted this in another thread. Hope it helps.
Well, I shot my 20 today. Wanted to make sure the FF was still on. I shot two shells of last years lot #s and got 195 & 183 in a 10" circle at 40 yards. I love this shell and Sumtoy .562 choke combo. Deadly on the turks.
I purchased a box of the lot# 5P-10P3593 (Bass Pro had these for this season) the other day and wanted to try and see how they compare. I ended getting 129 in a 10" circle at 40 yards. A decrease of 34% of shot from the 195 earlier. I used a bore snake in between each shot twice to keep things sort of consistent. There were large holes in the pattern and just not that all impressive. Wanted to give anybody a heads up who is looking to shoot the new Federal lot #. I hope you have better luck with them than I did. Luckily, I have quite a few boxes of the older lot #s.
First pics is the last year's lot # and then this year's lot#
