Hey Gary don't forget your little buddy down here in the southern part of the state. I could use some of them bad boys. LOL Just kidding, hope to see you come down to are neck of the woods this summer. Stay safe this winter. G2
Those paper shells shoot softer. Easier on your face, shoulder and overall performance as a shooter. Unless you haven't shot them they are less on recoil than the same loaded plastic shell. Get some and try it out. You will like those hulls.
My understanding and experience from loading Federal Paper hulls for years is that, every time they are shot, a little paper from the inside of the tube is scrubbed off. A hull on its third, 4th or 5th reload definitely has a weaker crimp. Upon ignition, there is less resistance to the wad and shot being pushed forward and the load does not develop peak velocity.
That said, I have made many a long shot with hulls that were on their last legs. I always felt that so long as I was into the bird and kept my swing smooth, a little lost velocity did not cause a miss.
There used to be a similar but opposite argument with plastic hulls. Whereas a paper hull remains smooth inside over its life, plastic hulls become rough and cause more resistance to the wad and shot moving forward. At one time, I believe that there was a company selling some type of coating to smooth out the inside of a plastic hull after it had been fired.
I try not to think about all of these issues when I shoot. I think that being a space cadet (empty headed) is the best way to shoot trap. See the bird and break the bird. I have had umpteen Federal Paper hulls separate in my 870 due to being reloaded too many times. I just pull out the separated paper tube from the barrel, ensure that I have removed a complete hull by counting the pieces and looking through the battrl and load another round. How hard can it be?
