I just pulled my bolt for comparison. Yours does stick out a little more than mine. But, it is not a lot more.

The click is rather loud when I dry fire. I think the hammer may be hitting the pin a lil to hard.

See my earlier post...an AK and SKS are built for Berdan primers which are harder that the Boxer primer used with Federal or most US made ammo. Any excess protrusion or an excessively hard strike can result in a primer penetration.

Try it with some Comm Bloc mil-surp and see if the problem persists. If the firing pin is good there should not be any primer blow outs.

Have a gunsmith or machinist measure your firing pin protrusion from the bolt face. If it sticks out .050-.065 like my SKS and one of my AKs did, have it trimmd back to .030-.035.
