Is there an issue with storing various plastic hulls in all gauges in my attic? They’re in plastic garbage bags so will be dry. Temps in summer will hit high 90s a few days. In winter, a few days will be zero degrees.

I used to keep mine in my garage (when I had a house with one) for years with no issues. Is your attic insulated so the temps stay somewhat constant? My garage was not heated or A/C'd but being part of the house it stayed reasonable as long as I kept the door closed

I have had them in high and low temperature areas over the years and just would kind of let them get to room temperature when I was going to load them. I now keep them in plastic 35 gallon garbage cans in the garage.

I keep the excess hulls in my yard shed, with the lawn equipment. Believe me, in Oklahoma, it gets danged hot in the summer and cold in the winter. Never had any effect on the hulls that I've stored out there.

Thanks guys.

I keep them in 5 gallon paint buckets, but a clean garbage can out in the shed would free up space. Good idea

Temperature isn't going to cause trouble. Moisture, and condensation, might. But as long as it's in a space that can breathe you shouldn't have an issue.

I have hulls from my hunting in Mexico back in the late 70’s that I keep in the rafters of my garage, (20ga) used them when I started shooting sporting clays in the 2000, worked great

Prior to relocating several years ago, my experience mirrors Vette's. I stored a supply of AACF hulls in 55 gallon black contractor bags stuffed into large industrial shipping cartons kept in my yard shed. The hulls survived snowy winters and hot summers without a problem. I don't believe there would be an issue storing plastic hulls in your attic (winter in International Falls might be an exception).

My stash of hulls currently reside in a row of double stacked 10 gallon storage totes on wall mounted overhead wire shelving in an attached garage.

I was just wondering about this very question. I wonder no more!

I don't know about temperature. Extreme temperatures can't be a positive thing but I can't remember ever losing a hull because of temperature alone. I have lost quite a few hulls to rust & corrosion. Few of us live in a region of as severe corrosion/ rust producing conditions as we have here. You can consider yourself fortunate if you don't in regard to corrosive conditions. Namely, tropical & semi tropical conditions of high humidity & high temperature like we have in Florida, the Southeast & the Gulf coast. High humidity will get you! I have been keeping hulls in at least a semi controlled environment that limits humidity & temperature extremes, namely a closet in the house. I haven't lost a hull to rust in the last 4 years. The attic worked pretty good too but temperatures up there get well over 100 degrees. Also, brass is not immune to corrosion & that doesn't even consider the effects of a salt atmosphere!
One encouraging development in relatively recent years has been the new super rust/corrosion preventative sprays. Tests have shown samples of treated steel exposed for extended periods to have survived with little or no rust or corrosion. WD40 has such a product as do others, now if I can find a place to buy some!

Winchester (Olin) stated in print ads many many years ago that their new compression formed hulls were made of polyethylene which is pretty indestructible stuff. I have no idea about the current AAs or other brands; maybe the same stuff. I have AA cf 20 ga hulls that are red in color. These go back to the 1960s and they are still just fine. Wads are a different matter. I’ve got wads that are so old that the plastic petals will easily break off when bent back. That plastic, whatever it is doesn’t seem to have the longevity of the hulls

I store my hulls, both once fired, and fired several times in unheated buildings. The only time I ever had any issues is when I didn't let them warm up sufficiently. They cracked at the 'roll'
of the crimp.

Buckets, boxes, bags, in garages, basements, barns. Over the years I have stored hulls in all of them. Some are pushing 40 years old. I have never run across an issue. Wads are thinner and more fragile. The hulls just keep on going.

150 qt totes work well for me and are stackable.
