Hello all,
I am hoping someone might be able to provide some info regarding a reloading issues I am fighting. I am reloading 308 mil brass and I am experiencing a problem with the cartridges jamming when they are loaded. If the round loads far enough, the gun will fire and eject the round fine, however, trying to cycle the cartridge out by hand is a futile task.
I have been through all the measurements multiple times and even seated the bullet as far down as 2.7 COAL without success. As a last resort I took some 220 grit sand paper and gave a cartridge that was sticking a once over. This allowed the cartridge to load and eject freely without being fired. I tried this again with a second cartridge with no success, however, with the newly roughed up brass I was more easily able to see where contact was occurring. It appears that the seating issue I am having is caused by the tapper at the neck.
With that said, I am using the Hornady 308 full length die set. The sizing die is set all the way down to the case holder.
Here are the measurements I am seeing (6 location from top to bottom):
Factory Reload Spec (Speers)
0.338 0.336 0.3435
0.341 0.3435 0.3435
0.4505 0.4501 0.454
0.4517 0.451 0.4553
0.4685 0.469 0.4703
0.468 0.471 0.473
Thanks....
