After cleaning my mini 30 (583) today and wondering the entire time why this rifle will not shoot steel ammo. I think this may be a solution and if anyone has any feedback on whether you think this would work or why it wouldn't work I would appreciate it.
I have noticed that with the tula ammo I have bought, the primers a recessed slightly more than the brass that I have which is Fiocchi. On the tula, it can range from 0.010"-0.015". The Fiocchi is pretty consistent, ranging from 0.008"-0.010" Is the extra 0.005" on the tula enough to make a difference of whether the primer goes off or not? If so then that is a problem that I obviously cannot fix.
After thinking about this, I remembered seeing that the firing pin in my rifle will actually go below flush on the back of my bolt, about 0.010." There is basically 0.010" of free play between when the pin is flush and when it is below flush. It also means that when the pin is below flush, the striker sticks out 0.010" more than it does when it is flush. When the hammer strikes, it only hits the back of the bolt, it does not follow through on the back of the firing pin. In this case, that means that the firing pin is basically going off of momentum for 0.010." Well in my opinion that would make for a "soft strike" especially on the harder primers in the steel ammo. So what I am thinking is that if I even just mill off 0.005" from the back of the bolt, then the hammer will follow through the extra 0.005" that the tula primers are recessed, and even if the ammo is not recessed it will still make a harder strike. Any feedback or opinions are appreciated, just figured i would share my thought. Thanks.
