The primer detonation was never a factor to me. It was the space the primer takes up that should increase the pressure of the load. But like we said it is a pretty minor load so it should be no problem. The Speer manual lists a 115 gr load range from 41. to 4.5 gr of Titegroup and a COAL of 1.135 but the Hodgdon load data shows a range of 4.5 to 4.8 gr and a COAL of 1.125. To the point of space left in the round, a double charge of 4.4 gr will not overflow but is obvious - lots of space. As a side note, I did test 4.1 gr of Titegroup yesterday and it cycles both a CZ 75b, a Glock 34 and 19 and does shoot a bit softer. In any event, before understanding that the 4.4 gr was a light load, I did weigh the completed rounds by headstamp. By headstamp the rounds were within about +/- 0.5 gr. A WSP primer weighs 3.2gr. So if there was a loose primer in the case it would have found it. So I'm shooting them. Thanks to everyone for all the suggestions and help.

Thanks. I do have the strong mount and checked there but only found three or four spent primers.

Great idea, thanks!

Thanks very much for replying so quickly and for all the ideas. I did very carefully check my load bench but did not find the primer there and it was not in the spent primer cup. I also checked the floor with a flashlight and even moved the bench and checked there. I did find one primer under the bench (at the rear of the bench) but I simply can't be sure that that's it because of the way I lost it and all the loading I've done recently. Here's how I lost the primer: While loading, the area around the shell plate became dirty particularly at station one, so I removed the primer (the one on top of the seater) and placed it on the bench (to the right of the press). I then cleaned the shell plate. Next, I picked up the primer to place it back on station one but in doing so bumped the completed cartridge bin with my hand causing me to drop the primer. Thinking that the primer was in the bin, I decided to proceed and later retrieve the primer upon finishing the next few rounds. Unfortunately, the primer was not in the competed cartridge bin. After looking everywhere else for the primer, I realized that it could have fallen into the empty brass bin (and into a case which was then loaded) due to the empty case bin's proximity to the completed cartridge bin ( I use the mount made for the RL550). I've made some mistakes with dropping primers but never this one. Since this could be a dangerous situation, I think the only safe option at this point is to weigh the cases sorted by headstamp in an attempt to find the primer. And I'm going to change my loading procedure to eliminate this potential problem from re-occurring. I'll report back when I get this resolved.

A primer inside the loaded round.

I just loaded 200 rounds of 9mm on a RL550. Load data is Ranier 115gr RN over 4.4gr of Titegroup at 1.135 COAL. have the machine setup with the empty case bin. After loading I realized that I was missing one primer. Without going into the scenario in detail the missing primer may have fallen into the empty case bin. If so then the primer may be in one of the loaded rounds. This means in one round I may have two primers: the seated one and a loose one. Question: if shot, will this cause dangerously high pressure? Thanks for any help on this one. I'm thinking I may need to dissemble the rounds but thought I would I ask on this forum first.
