Good time to understand how to do what you want to do.
Once fired, about as close to chamber size as possible.
The less you bend it, the closer it will fit.
Good time for a Datum line case gauge & an accurate caliper or micrometer.
Case in gauge, measure. This is the fired case BEFORE sizing.
Slightly bend case for size, see if it fits in the chamber.
If it does, case gauge & measure again.
Know exactly how much you need to bend the brass, and don't bend it anymore than you have to.
Keep in mind, you are allowing the brass to be 'Larger' than SAAMI/Factory, so you MUST measure and mess with the brass until its bent enough to fit that specific chamber.
It takes a little more fussing around since each brass will have a different rebound ('Spring Back') rate.
About everyone that tracks brass finds effective annealing, if not optimum annealing, helps with longevity.
I find annealed brass takes neck/shoulder sizing better since the brass is both softer & stress relieved to varying extents.
Keep in mind, you can go down a rabbit hole here,
There are TONS and hundreds of dollars of neck sizer dies with fractions of an inch difference, shoulder dies with micrometer adjustments, etc.
It's possible to bump shoulder back a little extra than YOUR specific chamber, and not effect consistency all that much.
This method will make the most stubborn brass fit the chamber, but you won't have brass that's 'Spot On' each and every time, this is simply because the difference in cases, but you do get to use common dies.
If you get a case that's REALLY stubborn and won't measure out, you simply stick a feeler gauge under it to get a little more shoulder movement. This is using a shoulder die and not a full length sizing die.
This saves you buying a set of custom, 'High Tolerance' case holders for the press.
It's up to you how exacting you want to be, how much time you want to put into each case everytime you reload.
