I hear you, now I need to find ammo

[Bill Zachow]

I stopped buying shells from RST when they sent me a flat of 16 gauge shells for my O frame 16 gauge hammer Parker. The shells had the lousy, overly thin primers that pierced on every shot. After 4 shots I quit using them as I did not want to damage anything from the blowback. I reload using modern 209 primers with no problem. When I mentioned this to Morris at a Parker annual meeting, he did not want to talk about it so this unhappy customer went down the road.

Unfortunately although reloading isn't for everyone it's the only way I can feed my old favorite and new favorite shotguns with the exact load I want. Once you get started you will never want to buy factory shells again.

I rather doubt Morris hand picked thin primers just for you. Piercing cheddite primers on Parker hammer guns is not uncommon, but the problem lays with your gun, rather than the primers. It is a clear indication that your firing pins have, just as many Parker hammer guns, worn to a pointed profile and need to be dressed properly. You may have had better luck with another brand, which most likely had thicker Remington or Winchester primers, but pointing blame at RST is pointing in the wrong direction.
I too have pierced Cheddite primers, but only in hammer guns, and rectified the firing pins right away, never having had the problem again. I would estimate I've used more than 25,000 Cheddite primers in 12, 16, 20 and 28ga.

RST uses primed Cheddite hulls. They are what they are. Possibly you have a firing pin issue?

I was worried about the damage in a hammer gun from pierced primers also but I was made aware that no blowback can get to the wood as it could in a hammerless gun. The firing pins are contained in the action with no way to reach the wood on these guns. With glasses on, I would shoot them with no worry.
