    45 Colt rim diameter by brand?

    I just picked up a rolling block in 45 Colt .my Winchester and Remington brass the rims only run between .504 and .508. Like many rolling blocks you have to be careful not to push the rim past the extractor but in this case on ejection often it does not extract the case at all. I was wondering if Starline or Hornady have a rim closer to 512.

    Perhaps a thin O ring of the right diameter might help.

    My starline 45 colt brass is .509”. Actually, it is between .508” and .509”
    Due to the price of primers, warning shots will no longer be given!

    Sorry right idea wrong subject. My thought was an O ring ahead of the rim to increase the diameter of the rim and give the extractor something to grab on to.

    The rubber ring, in the extractor groove, acts like a rim - enough to cause the round to fire and extract.

    I acquired 45 Scofield starline and the rims are .520!.i made a fixture and turned them to .514 in my lathe and the fit is perfect.
