reactive?..these are so thin that they just get full of holes..i have four to six of these a week..sometimes more
If I got one that still had some compressed gas inside you'd get a little reaction, at least with the first shot.
Maybe the ones made in the 70's and early 80's were made with thicker walls?

the 410a pink cans are thicker but propane tanks are a hole lot more reactive with incendiary rounds
