I've got data from most everyone under the sun and I forget which one it is that says to use the Winchester 209 and the Cheddite 209 interchangably. I have, and it is accurate information. I use them after a few shots and the primer pocket gets a tad loose. Then the Cheddite is the perfect fit. For all intents and purposes MY experience with them in 12, 20, 28, and .410 is they are the same as the WW 209. At least my chronograph and patterning board can't tell the difference, nor can I! If you do use Cheddite in AAs or such, you are stuck with them, 'cause they will strech your primer pocket a bit and now the Winchester, RP, and Fed will be loose. Not bad primers at all!
