I have a Mosin Nagant 91-30 and an M44 that I have been tinkering with using both boolits and jacketed. I noticed the primer pockets in the Grafs brass seems to be deeper than any other brass I have including another brand of the same caliber. The only way I have to measure is the tail end of a dial caliper but there seems about 10 thousands deeper than other brass.
I noticed it when I seated the CCI 200 primers. There was also a misfire with one load and a slow fire with another, it was 49.5 grs. of AA 4350 and a 150 gr. jacketed. The primer fired but didn't ignite the powder. I thought maybe the primer was seated too shallow and the primer didn't fire properly. I loaded a few more with some Fed Mag primers and they seated properly and fired fine. The CCI primers were a good bit shorter than the Fed primers. This same primer and a load of 4198 with cast does great in the M44.
I am not sure what happened, primer not seated properly, bad primer, too slow powder, need a mag primer or all the above. I don't like the primer pockets being deep, I have had this brass for a good while and haven't had any problems.
Anyone else had any problems with varying depth pockets and primer length ?
