Peppering

I was at the range today and encountered what I can only describe as a peppering effect on some of my rounds. I was firing my 9MM Makarov which produced what felt like small pebbles hitting my face. This has not happened previously. This was only my second time loading for this weapon.

I am wondering if I seated the bullets too far in and created an over pressure situation? I did not notice any deformities in my brass.

Could it have anything to do with the primer? (doubt but have to ask). I have been using CCI and recently received a shipment of Tula. So I had rounds with each today.

Load data:
93 grain lead cast bullet
4.1 grains titegroup
Tula and CCI primers

I would appreciate any thoughts on this.

Thank you.

First question is whether your gun is a 9mm Makarov or a 9X18 Makarov, which are two different cartridges.

If it is a 9x18 gun I will venture a guess that you are over maximum charge with 4.1 of TGroup. See http://data.hodgdon.com/cartridge_load.asp


You need to give us a round OAL and confirm the cartridge at this point.

If a direct blow-back, you may be getting premature movement of the slide and your feeling powder kernels hitting. You may need a heavier spring or the load may be too heavy.
I only know of one 9mm Makarov--what other Makarov is there?
Not thinking 9x17 (.380 Auto, 9mm Brownging short)?

Got the load wrong, 3.4 grains. Sorry, 4.1 was for my 9mm. OAL is .9675, however, I have been having issues with inconsistent bullet sizes as they have been varying. That is one of the reasons I thought it could be the seating.

Thanks again.

Try a different powder, one not so 'fast'.
