What ammo? 

[gregtpal]

I would start by verfying firing pin not gunked up but that probably not it.  Then check primer seat on ammo you are using  & try to find other slugs that arent seated as much or maybe just fire better than what u are using.  Id start with Hornady since easier to find.  Could get expensive.

[Michael Britt]

Serial# N221351 not sure what year that makes that it?

Using Horandy SST 2 3/4"

Never happened before. If I had to guess, probably only has like 20 shots through it in 3 seasons.

No problems before today?  Did you do anything recent like disassembling to clean?  If not, pull the bolt, break it down, give it a good clean, and try again.  Do not fiddle with the firing pin as you may change its depth inadvertently.

Images always help.  Have you any of the light strikes?  Also, did you try a second shot on the light strikes? 

In any case, get a caliper and using the depth blade check the primer seating depths.  Rank the shells from shallowest to deepest. Record the depth on paper and number the corresponding shell.  Go back to the range and see if you can determine a depth at which they stop firing. 

A quick interwebs search shows normal factory seating depths range from 3/1000" to 5/1000".  I usually set my rifle primers to 7/1000"; with a good strike.

Usually, I would  try the ammo in another firearm and/or try different ammo in the 220.  However, that may not be feasible with slugs. 

If the problem persists, adjust the pin incrementally.   I have a Savage bolt that is pretty easy to adjust.  

Try dry firing.  Does everything "sound" good. I had a similar problem recently with a rifle that was not firing and you could literally hear the difference in the "click."

If you reload, you can always put some primers in an old hull to get a nice strike as you adjust the pin.

I just read the user manual again. Apparently the Accutrigger has some weird safety mechanism where the sear will be blocked, you will hear a click but the firing pin will not strike the primer. This is if the trigger is not pulled perfectly rearward. Maybe I developed a bad habit today? Only time will tell...

You guys are reinventing the wheel. 
Call Savage, send them the bolt, they will replace the weak spring. 
That was regular practice on many 220s early on, yours must be one of them. 
 

[Michael Britt]

If you guys didn't see in yesterday's thread...5 light primer strikes yesterday...buck got away!

I looked up my paperwork, bought the 220 in 2019, it should not have that issue, yet it does!

I'm going to call Savage tomorrow. 😬

[Pathman]

That’s your best bet, I shipped my bolt back years ago and never had another issue after that.

Did you leave the bolt cocked from last year?

Great question. Another suggestion....when you pull a bolt action back, squeeze trigger prior & while closing bolt. This will prevent dry firing and firing pin spring from being compressed.

I will sell you an ultra slugger 20 for 2 grand, pm me if interested

I did that on purpose when I bought the first iteration of the Kriss Vector, spring was so tight.

Spoke to Savage today. They said they would fix gun under warranty but I have to mail the entire gun to them.

OR 

I can have a local gunsmith fix and they will send him parts under warranty.

Would you pay postage and risk mailing out your gun in this woke world OR pay a local guy labor and have much better turnaround time especially considering it's hunting season?

Seems like a no-brainer...
