357sig Don't you mean deburr the mouth of the case instead of the rim???
I load a lot of .30-30 for a mod 94 Winchester. The .30-30 case is a bit tender and can be damaged real easly when reloading it. The most critical step is crimping it. if you crimp it too much the case bulges or crumples. If you don't crimp it enough it can depress the bullet when in the tubular magazine. This can be remedied by using a Lee factory Crimp Die (FCD). You need a resizing/decapping die, a seating die (to just seat the bullet to desired depth which is at the very top of the cantilear) and a FCD for setting the crimp...Like any cartridge you will have to experiment till you are satisfied. As 357sig says about head space. I have my resizing/decapping die set .030" off of the shell holder to allow for the head space on a 57 year old "Jack Handle"...
My cases are pretty much fire fitted to the chamber.
Might I recommend a good round that works for me both on the range and on the hunt...Prime Winchester or Remington cases with a CCI 200.
Drop in 32 grains of W-748 and top it off with a Speer 170 grain FN...
