    I shoot a 7mm Weatherby Magnum. I'm on my 5th loading and I have only neck sized after the initial firing. I have not bumped the shoulder back yet on any of my brass. I have not had any trouble chambering any rounds. Should I be bumping shoulders on a regular basis?

    You will get alot of different answers here. My opinion is that if you can load the cartridge without any abnormal resistance, dont worry about it. When they start to feel different, it is time.

    Don't bother until they become hard to chamber.

    My loads are starting to get resistance, should I measure the shoulder on a once shot brass and set it to that measurement, or bump it back a bit further?

    Also can this be performed with a RCBS Match bushing FL die, but with out a bushing?

    Would I just mark the brass and insert till it bumps the shoulder? Or will this slim down the body of the brass also?

    Thanks in advance.

    Just push the shoulder back .001" from where it gets tight and see if that takes care of it.
