I have an issue with my Lee collet die with the sizer getting stuck inside the die and crushing my 300 win mag cases. Help Mr wizard…

Holy shit, 6 of 'em dude, 1 or 2 wasn't enough to pump the brakes? 😜

Setting up a Lee Collet Die is sort of a "feel thing", screw it in like halfway and test it by slowly running a case up into it while trying to get a feel for how it engages the cases, and then adjust to taste. As you can tell, it doesn't take a whole lot of force to do a whole lot.

There are different setup procedures based on the press being used. Did you follow the instructions included with the dies?
Throw the instructions away.

Then read mathman’s instructions. Print them out if you can.

Thx everyone for your input... I will try mathman's instructions.... and yes I followed the Lee instructions for my rcbs press. So much for instructions. The die worked great for 15 rounds then you saw what happened after that :-(

OK... after reading mathmans procedures life is good. I am able to get a great tension on the necks without crushing anymore. I can even use the rcbs with cam-over... thx again for all the help.
