That's why you use a body die to bump shoulders when chambering gets tight. It's a very simple process.....neck size, bump shoulders as necessary.
Redding Body Dies are really versatile and give a lot of options. I've got some that have been converted to bushing dies and some that I've opened the neck area up to size to a specific diameter. They are great for necking down cases as they can get all the way to the neck/shoulder junction if need be.
Lots of ways to skin cats with dies...basic math and some thinkin' gets you most of the way there.
FWIW, this is a standard Redding 243AI full length die that I modified to take a bushing
and size all the way to the neck/shoulder junction:
Redding Body Die....converted it to take a bushing to size to .060 ahead of the neck/shoulder junction:
Another bushing conversion....this started life as a Redding small base Body Die:
