Are RCBS trimmer pilots supposed to be so tight? My .22 cal. pilot is a pain in the rear to get out of .223 cases, my .44 pilot puts a small bell on my 44-40 cases(the chart says the .44 pilot is for .422-.430 diameters).
I thought about putting a pilot in my drii, wrapping some 400 grit sandpaper around it, and taking a little off, is this a bad idea? |

What type of "trimming" are you doing? If you are simply trimming case over-all-length, I don't see how your method would hurt anything. If your trimmer also cuts the outside of the neck, I would leave it as is and just work with it. Use oil liberally and slowly work the brass over the pilot.
I mention this because I have seen some of the RCBS trimmers that actually trim the length, the outside of the case neck, and champher & deburr all at the same time. |

When to trim? Trim to what? Before or after? I would say based on my the pilots size trim before sizing, it is more about opinion than logic, when I use the hand crank trimmer with the pilots that never fit, I trim first, that way the pilots always fit and there has to be a reason after all RCBS made the neck sizer and the trimmer pilot,why would RCBS build failure in to a produce, after sizing the pilot is too tight and sizing the neck down lengthens the neck and pulling the sizer ball through the neck shortens it, I trim first, more times than not I use a form/trim die FIRST, the form die is not a full length sizer.

Puma,
Here's an idea to look into. I rarely neck turn to uniform my brass, but I'm considering upgrading some equipment to try this again. I noticed in a recent Sinclair International catalogue that they offer a uniforming die that takes various caliber mandrels to uniform the case neck inside diameter. This is done to insure they fit the neck turning mandrels (without being too tight), but might work for your trimming. It's also a great way to uniform the neck tension before seating.
The Sinclair Generation II Expander Die costs $24.95 and the caliber specific mandrels are $8.75 each. The mandrels are .001" under bullet diameter. Something for you to look into and consider, anyway.
Stay safe...shoot straight. |
