Seems that I have an 84M action that started to have lite firing pin strikes and not making things go bang!

After a bit of research it seems that this is a known problem with a weak firing pin spring, and is fixed with a replacement spring. I guess the new spring is 1/2"- 3/4" longer with still having the same amount of coils.

With no Canadian distributors anymore, you have no choice but to call Kimber and order direct from them. No problem, bit of back and forth, and then learn that it is only phone sales they do. $7 spring, with a $75 shipping fee is a little outrageous, but what choice does one have.

Has anyone had, or heard of anyone having such issues with their 84M actions?
 
The research I did came up with the wolf springs as well, but some said the diameter was too large to fit inside the bolt. Maybe a 84L action compared to the 84M action.

I took the known route and ordered direct from Kimber.
 
Yikes, that's pretty steep for a spring, sorry to hear it. If anyone knows of a better (cheaper) solution, please add it here for the rest of us.

Also my Kimber had a bunch of grease in the bolt, I disassembled it and cleaned with brake clean, no issues after that.

Anybody running a Model 70 style action should be doing this. I mean, everyone should, but the M70 and M98 family strip so easily that there's really no excuse. I've seen bolts so frozen up that they wouldn't fire. Flush them clean with brake cleaner and then lube with powdered graphite. You're laughing.

Have you checked firing pin protrusion?

The strikes on the primers look good. No real reason to not go bang. Last outing before looking into this I had 5 out of 13 rounds not fire. And in no particular order. Just some would, and some would not. Even tried on those that did not after again, and still a no go.

Initial thoughts were bad batch of primers, but in 3 other rifles I have used those primers in have been no problems. First time it was a single round, out of a batch of 15.

I will disassemble maybe tomorrow and check out the inside, while I await for the new spring.
 
reloads? pushing the shoulder back to far when resizing can cause case clearance issues which result in light primer strikes

What primers are you using now?
 
I’ve had a similar issue with reloads on my 84l. Turns out certain brass with Remington primers was causing the issue. Could have been I wasn’t seating the primers all the way. Switched to federal exclusively for that cartridge and problem went away
 
Using cci 250 primers.

Took bolt apart and checked internals. All was good and clean, slightly oiled still, nut gummy.

Trying some other nickel brass, if the weather is decent tomorrow for a range trip.

Pulled bullets and powder and tried to fire off primers in another rifle, same caliber, and was a no go, but they were already somewhat strikes so maybe pin not reaching them.

measure base to shoulder of one that fired and compare it to the base to shoulder of one that didn't fire, you have a hornday case gauge I take it.......

There's the problem, CCI are about the hardest to light of the commonly available primers. Whether it's from harder cups is up for debate; but that they have a less sensitive compound than Federals, and less "Heat" isn't.

The Kimber firing pin is very light and comes with a 37 lb striker spring and needs it. A Rem 700 has a heavier assembly and gets by just fine with a 24.

Light hit meets hard primer and you get what you've got. (Some of the time) Stick some Federals in there and I bet your issue goes away. If it doesn't work with those it won't work with anything. It'll give you something to do while you're waiting for your spring.
