Every gun is different and you may have to move the shoulder back a thou or two for it to chamber. Also when you get the die set and start loading never use the middle die, the neck expander. Just chamfer the mouth of the case just enough for the bullet to sit on top of the case. I use the chamfering tool in the Makita type battery operated tool but if you don't have that you can use one of the little bomb shaped manual tools. With the battery operated tool it only takes about half a second to chamfer the mouth of the case.
Not using the neck expander keeps the neck tension in and holds the bullet fast. Do a light crimp just where you can just see the mouth of the case turning into the cannellure.
