I started playing around yesterday with some once fired cases. I will tell you that I am not all that smart when it comes to reloading, I am the grasshopper here, I could not get a dummy load to chamber in my Remington Sendero 300 RUM. I even tried seating the bullets "berger 185gr" to the same depth as some factory remington ammo and they would not chamber. Then I tried again this morning and reset my full length resizer die in the press and went to run a case up in there and whamo stuck the case bigger then you know what ***** Can't get it would and cabelas does not have the stuck case remover and can't get it to move, so I bought a new set of die's. Can anyone tell me what I may be doing wrong here??????? Please Chuck It was a cold morning and could the die have shrunk???? causing the case to stick????
