When did manufacturers quit making paper shot shells?
I'm guessing back in the 1960s? |

Quoted: I seem to recall an old friend of mine saying they used to group tighter I believe what one of the contributing factors to groups opening up or staying tight is how deformed the shot becomes as it travels down the barrel. The rounder the shot stays, the tighter the group. Perhaps the paper hulls being softer than plastic hulls, the shot stays rounder. |

The rounder the shot stays, the tighter the group. Perhaps the paper hulls being softer than plastic hulls, the shot stays rounder. Pattern spread is from lateral velocity of the shot. Lateral velocity comes from a variety of sources, one of which is strain energy as the shot column is compressed, causing a bit of elastic energy to be stored as the shot is making the trip down the barrel. When the shot column hits the muzzle, the confining effect of the bore is gone and the strain energy causes the shot to achieve lateral velocity. This is spread. The strain energy between two spheres is small, especially when they are lead but it is there. Think of billiard ball reactions, they bounce off each other because of strain energy from impact. Winchester has come up with steel shot that is not spherical but polygonal, having a finite contact patch area with the neighboring shot instead of a point as sphere-sphere contact in round shot. Point contact between two spheres has infinitesimal area. This reduces strain energy between the shot so lateral velocity is reduced. Even though they are not spherical, the impact on pattern is minimal compared to the reduction in strain energy. Paper hulls were loaded with felt wads and had decades of development to control pattern. When polymer hulls were introduced, they had not worked out the wad configuration. Modern hulls shoot just fine. |
Federal still makes a limited run of paper shells each year mainly aimed at trap / clay shooters. They are nice for reloading if you are setup for it, but limited in use as they get pin hole burns near the base after a while. If you enjoy reloading them and get the hulls for free, go for it otherwise these days I would consider them a novelty, perhaps a reminder of days gone by at best.

Quoted:
Anachronism. Winchester AA and similar quality pattern great. No need for paper any more. Winchester AA's used to be the greatest thing since sliced bread for loading. Then the went to the tapered / HS hull and now a large percentage of reloaders will pass on them. Remington makes the best reloadable hull, even the steel based ones, and I would put seconds to Federal Gold Medals...ribbed.. |

I used them in auto loader for clays. Slicker. I used AAs in my O/U. I can't believe they have lowered quality on AA |

Some say they are just behind in orders. I do believe that if Winchester were to return to the old style AA hul it would boost business for them. Its a classic.....
