Seeking softest shotgun primers out there

[Tokarev]

One of the guns in my collection which I like very much has a weaker spring, but it's not really worth repairing.
Are there softer shotgun primers than CCI 209 that I am using most of the time?

What type of shotgun is it?I had a stevens sxs that I thought had a weak spring but it turned out to be a worn fireing pin.Alittle hand filing on the pin at the stop and it went back to normal...Robin

I know the condition of the parts and not going to do any repairs. Just looking for experience with different primers.
There could be found opinions on pistol/rifle primers softness, but I could not find same for shotgun primers.

[Swamp Man]

There is a brand call RIO that may be softer.

I would try Cheddite primers as I have heard that they are softer.

[UNIQUEDOT]

Yep cheddite is the softest shotshell primer I've yet to encounter. They are cheap too and can be substituted anywhere win 209's are called for.

[Tokarev]

Not so cheap up here though, about the same as CCI.
