| Today while shooting my 44 mag I had 4 rounds that failed to fire. Upon inspection of the rounds I discovered the primers were seated much deeper than the others. At first I thought my Ruger was having some light primer strikes but after seeing the extra deep primers I knew that was the problem. These loads are made with Star Line brass and the primers are Remington large pistol. I will decap these and try some CCI primers to see if they will work better in these deep pockets. |

Quoted:
Have reloaded 1000's rounds of Starline brass w/o issues. Not 44Mag, just 45LC and some 38 Sp. Have used both Winchester and CCI primers wo issue too. Is this new brass 1st load ? Yes, this was first time on this brass. I have 500 of these and noticed that of the 100 I have loaded these were the only 4 that the primers were deeper. I'm guessing these are just a fluke in this batch of brass. I've never had an issue like this with Star Line brass. |

Quoted:
You can get failure to fire when the primer isn't fully seated, the first firing pin strike energy is dissipated seating the primer, they normally fire on second strike after the primer is fully seated. Might check this as well. They were fully seated, and then some, so I am thinking these few pieces of brass had too deep of a primer pocket. I tried re-shooting them several times with no luck so I just pulled them. |

When I got my S&W Mod 629 I ordered 500 Starline virgin 44 mag cases, I have had absolutely no problems with those cases, nor any of the other Starline cases I have bought. Anything made by man can have a bad product from time to time, but overall their quality is extremely good. |
| That should be fairly easy to check with the depth mike end of dial or digital calipers. Decap the culprits so as not to bend the case head rim and record primer pocket depth. Compare to new case primer pocket depth. I am getting .118-.119 depth on my new 44 mag cases, R-P nickel plate. |
