Thread: Misfires with Tikka T3 and CCI Primers

Is anyone having or had any trouble with misfires with a Tikka and CCI Large Mag primers? A mate has had this happen a couple of times now in the field with his 270Win. The primers are NOT getting seated to deep.

I'm using a Rem700 in 270WSM and am using the same primers(from the same batch/box) and haven't had any issues.

Has your mate cleaned and lubed the firing pin in his Tikka lately ?

Some of them can rust quite badly and if bad enough there is potential it could contribute to a light firing pin strike.

+1 on that. I had mine wet a couple of times and took a while to clean it. Rust was forming just forward of the spring where it seats against the bolt casing. Would be first thing to check.

why is he using magnum primers in a 270win anyway?

Have you tried finding Large Rifle primers lately? Also, he's shooting 1/3 MOA with this load combination from a unmodified $1000 rifle, so not keen on changing thing at the moment.

why on earth is he using CCI primers ,are they cheap or some thing.
CCI ammo /primers etc always where cheap & we get what we pay for .
I'd start with some better quality primers before you blame the rifle.

This is what I was thinking too. I recently spend a week around Dusky Sound hunting and fishing. Most of the guys in the group had Sako's and most had never had the bolt in bits to clean. They very surprised at the rust forming on the pin around the area Gibo mentions.

Did he pull the projectiles out of those struck rounds?.......did powder come out ?

When I was reloading for my rifles I started out with CCI primers and had a lot of misfires out of them then I changed to another brand of primer (PMC) and never had another misfire since then I have had no faith in CCI primers and refuse to use them again

Had a couple of "hang fires" with cci large rifle magnum primers in a 7mm rem mag. Put it down to possible mix up with my large rifle ones???

I've never had any issues with CCI primers, over 3 or 4 different cartridges. Only had misfires with WLR's.

Always have used CCI primers never had any problems either. Both in 6.5x55 and 223

Yeah I use CCI450 and have no problems


Have no problems with CCI .22lr ammo either

CCI 250s are "harder" in the cup making it more difficult for a weak firing pin to ignite them compared to Fed 215s.

Also they are "weaker" in the spark than Fed 215s so won't ignite slow powders in cold conditions reliably esp in the bigger magnum cases.

Thanks guys, this is what we were thinking. Harder cup and most likely a dirty bolt/pin.

This has only happened twice, but don't want it to happen at the wrong time. Again, my Rem700 has never, ever had an issue
