I think loading rifle cases with light loads is the potentially most dangerous procedure because it is difficult to compare the powder levels in the deeper case. When I am loading these, I use 2 loading blocks. I put the primed cases in one, base up. I then move each loaded case to the other loading block as I load them. I have experienced the no powder bit and, on one occasion, loaded 20 cases without primers. I had bullets seated in almost half of them before I noticed the powder droping out of the base. I thought I had them primed before I went to lunch.[/QUOTE]
Done that too. Felt like a dweeb.
One thing that happened to me that I haven't figured out the cause yet was while loading Cowboy loads for my .30-30. I used a Hornady progressive press to make 500 cast bullet loads with a light charge of Red Dot. Out of the 500 loads, two of them were not like the others. For one thing they sounded and recoiled like a hunting load rather than a light Cowboy load, like the other 498. Both fired cases also got stuck and had to be removed by tapping them out of the chamber with a cleaning rod inserted from the muzzle while a friend was pulling on the lever. And lastly, a mirror image of the bottom of the case was imprinted on the bolt face. To this day I can still read the inverted letters from thet R-P case.
Any thoughts on what could have gone wrong?
