Just got a new Hornady LnL AP.. and new to reloading 9mm cast (PC'd).
Pulled a few 9mm bullets and they are getting sized down/swaged on seating from .357 to .355. Barrel slugs at .3555, so loose fit.. The seater is properly adjusted, it's just that the expander isn't expanding the case enough and I'm getting terrible accuracy.
Same is happening, but less so, with my 45 ACP. I've been reloading 45 for a while now on a single stage.
The PTX expander for 9mm or 45ACP aren't doing the job. I tried adding my current expanders (Redding, RCBS); and they aren't opening up the case enough for my boolits either.
So, was wondering what the options are out there for a larger size expander? I saw the NOE plugs that work with the Lee universal expander, and saw the ones on Buffalo Arms that would work in my Redding/RCBS dies. Any others out there that are better? I'm thinking the .356-360 plug for the 9mm, and .452-456 for the 45 ACP?
