I started reloading a couple of months ago and have a load worked up that shoots great in my 7 mm. Now for the prolbem I have. This morning I used one of my reloads to harvest a deer, after i got home i went to unload my rifle before I put it up and as I pulled the shell out after I shot the deer, powder came pouring out of my gun. The bullet was in the rifling and the shell without the bullet just came out. I have never had this happen. The bullet was not stuck in the rifle hard either,I took a cleaning rod and it just fell out. Did I do something wrong when loading the bullets? I have shot maybe 30 rounds loaded the same way and all have shot great and group great to any replys would be greatly welcomed
