I load .45ACP, .40S&W, and .30-06 with no problem. I am using Lee dies on a Lee Challenger SS press. I am also loading .270 WSM for my father, and it doesn't go so well.
I understand the WSMs are harder to load for. With new Winchester brass, loads are perfect. With the same brass, once-fired, they were all but impossible to chamber. I am using the same amount of lube that I use on .30-06 (only on the body, none on the shoulder), and have my die set to cam-over.
When I mic'd the brass, the only thing I can see is that the shoulder is not getting pushed back far enough. I pulled the bullets, and slid a 0.018 feeler gauge between the brass and shell holder. Now, the shoulder is closer to specs, and chambering easier, but not like factory ammo. It still takes more pressure to close the bolt than it should.
So, do I need to shave some material off the bottom of my die, so that the brass will go in further, or is there something else that I am missing?
