So related update. not about anyone complaining but just something interesting. I tested my loads on a chrono and also tested some of my friends and some stock ammo as well. Only my friends loads where near expected data shot out of his Browning CTX. All the loads shot out of my Mossberg 500 as well as most of the loads shot out of my 1100 with a 22 in slug barrel was a minimum of 500 fps over written data on the factory box or my load data. And in some cases 1000-1500fps over. The really hot load was a factory super sport AA not legal for trap but the box said 3000 and i was getting 4400-4500. This box of ammo also kicks like a dang magnum so it could be an odd factory box. The 1100 had a open choke and my mossberg was a full iirc. I am planning on doing some more testing; Not because of my original question on the thread, you all alleviated my fears, but just because I am curious now, I just thought it was interesting how much a difference there was. edit: This is all off memory, my chrono decided not to record my results cause my phone didnt connect right. But Me and 2 other people where kinda floored by how much a difference it was compared to what we expected. When i test more I will make sure the app is recording.
Methinks either your chrono needed recalibration, or it was being used incorrectly.
Winchester AA's factory rated at 3000fps??? Maybe 1300.....
I guess a third possibility is memory loss?
