I've got these 100 grain Speer "plinker" bullets that are half jacketed, half lead round nose. They're meant for .30 Carbine and other .308 groove rifles, but since it's jacketed and can take high velocities, I'd like to use this bullet in .327. The problem I'm having is the bullet's diameter is measuring .3075" and .327 is meant to use a .312 bullet, so after sizing and with a minimal flare, there still isn't enough neck tension once I seat and crimp the bullet.
I've never found the need to buy an undersize sizer die before, but this may be one load I think I'll need to. Does an undersize size die squeeze the neck enough to increase the tension?
Also, given the brass is being worked more, how much shorter will the case life be after using an undersize sizer? My intention is to load these hot as that's the point of using this jacketed bullet.
