Question for Re-Loaders

Diver43Diver43 Senior MemberPosts: 11,498 Senior Member
I made three dummy rounds while adjusting the seating die.  First set too deep, second made small adjustments and got it set, third, just to make one right the first time.
Anyways, after I pull the bullets, do I need to resize the brass?   My Google-Fu is usually pretty good, but each time I looked, one said yes, the next no, and another said sometimes.
What do you guys say?

    I would. Your neck tension is going to be different if you don't. Start from a known baseline. #1 rule of handloading.....change only 1 thing at a time.

    Thanks
    I was thinking, especially for the one that seated too deep
    None have primers so its easy

    If they were your .357's the inertia bullet puller generally will not entirely pull out the crimp applied making seating a new bullet quite difficult. In other words, resize and re bell the case mouth.

    Didn't know that. It is filed away for future reference.  With these I didnt crimp, just set the bullet to proper depth.

    Excuse my ignorance but if you don't crimp revolver rounds couldn't recoil cause the bullet to shift in the case and cause problems?

    Will you crimp when you develop live rounds?

    Yes I will crimp live rounds.  These had no primer or powder 
    I was just adjusting the seating die.

    Yes,  resize so you are starting from 0

    also, fwiw, you may want to consider keeping those loaded dummies.  Take a sharpie and mark the LOA on the case.  then when you need to adjust the seating stem - and you will, you can use that as a "get close" stop gage.  

    its not like you wont have to make minor adjustments after that, but it will get you close.

    have fun

    I had made a few 125gr rounds that went together easily, from a handful of bullets and a bit of powder a co worker gave me.
    I finally received the bullets and powder i ordered

    Asked and answered, so a tangential but related item:

    If you are not using a separate die for crimping, you'll need a new "dummy" when testing the proper die position for the taper crimp desired (RCBS, namely).  The bullet is pressed to it's final depth in the case while crimping occurs.

    The same-but-25-extra-dollar solution is purchase a separate taper crimp die OR buy a used bullet seating die and gut it of all the internals.  I like this option because I like taper crimping after the bullet has been seated.  It un-complicates crimping 44mag and 44spl using the same bullet seating die, for example.

    I double-prefer the separate taper crimp die for EVERY cartridge.  My 44spl and 44mag have separate crimping dies with the lock nuts set-screwed in place and labeled with a paint pen.

    There's enough going on...anything which uncomplicates the setup is a plus.
