    Also, what would y'all (markm, anyone) say is the least amount of steps/work/processing that can be gotten away with for loading just "FMJ basic ammo"?
    Rifle is always a little more trouble than pistol due to the case lube removal. For me: decap, clean, lube/size/necksize, tumble off lube, prime, and load.

    I could skip trimming on blaster ammo due to no expander ball, but I run all of mine in the Giraud because it chamfers the neck even if nothing gets trimmed.

    Some reloaders use a expander die on the up stroke of the ram to reduce neck runout. On the down stroke if the case has any extractor dings in the rim it can cause the case to tilt in the shell holder.

    Does a progressive press change these dynamics? I do not understand why no lube on the down stroke especially with wet tumbled brass. I do not own or ever used a progressive so forgive my questions.

    I use a Rockchucker press and Forster benchrest dies with their high mounted floating expander and lube my case necks. The neck of the case is held and centered in the neck of the die when the expander enters the case neck. And on the down stroke of the ram the expander can not pull you necks off center inducing runout.

    As a new rifle reloader, I have already learned a lot by reading this discussion. Thanks everyone.

    Markm, I have a question about the type of neck expander die you mentioned in Post #14.

    Is this the type of die that you are referring to?

    Or this?

    So far, I have been using a full length (not small base) sizing die. To help reduce expander ball friction, I have been lubricating the inside of the neck with a Q-tip using the same lube that I use for the case (Imperial Sizing Wax). But your suggestion for using the expander type die intrigues me as a way to reduce the cold working of the case neck.

    If you want a good neck expander die then get the Lyman type "M" expander, you will have .003 neck tension or bullet grip. And bumping the case mouth on to the .226 step of the expander insures straight inline bullet seating.

    Me, too.

    It's threads like this that keep me coming back here.

    I have the second one. I have not tried the M die. The RCBS works for me well enough that I've not looked at other options.
