Had an incident, want to share.
So Skip you are saying that you guys with progressive presses are eyeballing every round you make to see if it has enough powder and can tell if it is off?
I know there are powder alarms but who much does it take before the alarm sounds?
Son in law #2, his wife (our daughter #2) and their baby came to visit for Christmas. He has been so busy at home, he has not been able to load for the Glock 22RTF I gave him so, he just brought the components here and we are going to load them up for/with him.
Since it was my gun, I have a load worked up for it, 6.6gr SR4756, 180gr Ranier or Berry plated bullet and a longer than normal OAL of 1.125". That thing put that load out at 1000fps or just under from that firearm. It was safe and never gave me one piece of brass that looked "glocked", never. Win/win.
The load we decided on when I bought my M&P 40S&W full size was one to mimic our son #2's load for the duty gun he was issued. They use a 155gr bullet at 1200fps or close to it and we went to Longshot to develop that one. Lower pressure yet with more velocity. Although, we didn't need to worry about it because it has a fully supported chamber.
Well, as Rule asked, how do us guys that use progressive presses check powder charges. I mentioned that I looked into each case. He then asked how I could tell the difference while doing so. Tonight, I proved that it can be done and done successfully.
Case in point: Loading those 40S&W mentioned last and for this particular run, I did not put the powder alarm on my XL650. Now, I was doing 100 rounds every 10 minutes or so, not the fastest but, fast, when I went to set a bullet on a case with powder in that station. I said: "Uh oh, got a problem." And I cleared the press. Upon examination, the once fired brass that I had purchased, nice cleaned nickel plated stuff right from the original bag, had one problem, must have been some green house flies in the seller's house that decided that one had to die in that bag of brass! Well, that one case had the remains of one of those flies in it. Since my case fill is a lot, it was a simple thing to see as that case came spinning into the bullet seating station.
Easily removed and back on to loading. The reason that it was easily caught was because of case fill. It didn't cause the powder to run out by any means, but, it did raise it enough that a trained eye could tell the difference.
So, when I am not using my powder alarm, I use my eyes more, pay closer attention and, with enough practice, it can be done successfully. It really helps on this particular machine because there is another filled case on the shell plate at the same time to compare to......
