7.62X54R surplus split case question

[LigersRCool]

I took out my 1939 and 1925 Mosins today I was using 1972 Bulgarian surplus 7.62x54R ammo with them.
This is my first time firing these rifles and also my first time ever shooting surplus ammo. I guess I just wanted to know if the case split is "normal" or is it indicative of an issue with the rifle. I did not notice anything different when these rounds were fired. Could I be creating these splits when I am pulling back on the bolt?

1939 Tula - 2 of 60 had the splits and 1 other had dent or start of split. Also sample pic of firing pin strikes.


1925 Izhevsk - 6 of 60 had splits. Firing pin strike samples also.


Thanks

Loose chamber, cheap surplus steel cases, probably nothing to worry about. If it bothers you, run it up to BP Tactical for a look see.

Thanks, yeah I figured it was probably the cheap steel cases, but like I said my first time shooting surplus so just wanted to ask.
I figure I'll leave pictures of the rifles....I refinished laminated stocks I found online..the original stocks I just cleaned the cosmoline off and are sitting in the closet.
1939 Tula is the top one and 1925 Izhevsk Hex is on the bottom. I really liked shooting these rifles. Currently working on a M44 and two Type 53s LOL I got a Mosin bug and found them all for great prices. Again thanks for the info.

i have seen this happen with the Albanian surplus that i got a number of years ago. no worry, still shot fine.
