Loading New Brass

I am loading 9 mm ammo using unused (NEW) brass. In the Square Deal B manual it states that unfired (virgin) brass usually does not require full length sizing. I have not made any changes to the machine and am using it as I would with used brass. I find that when the brass gets to Station 2 and I pull the handle DOWN to dispense powder into the brass, when I push the handle UP to move to Station 3 I have to exert a lot of force because the expander/powder funnel is really tight into the brass. Is this common with unfired brass or is there some adjustment that can be made to avoid this problem. Thanks for any help.

RE: Loading New Brass

I had the exact same experience when I used to load on a Square Deal B. It was ONLY with 9mm, and it didn't matter if it was new brass or brass that had been fired several times. I just learned to live with it.

I didn't have that issue with 38 spl or 357 mag brass, only 9mm.

If you scroll down, you will see my post about this, along with Dillon's response.

RE: Loading New Brass

New brass sticks to the powder funnel more than fired brass. Once it starts it will get progressively worst.

Clean the funnel off of all traces of brass. Best to tumble the brass in used media, or with a polish compound, to smooth all surfaces if you can. At the very least, lube and de-burr the cases. I use a spray lube in a plastic bag, giving the cases several sprays and working them around. I dump them out to dry. Then load. Everything should go nice and smooth.

Some will point out that you do not need to lube cases with carbide dies. The powder funnel is not carbide. Fired cases are dirty and will run smoothly because of the film on them.

RE: Loading New Brass

Had the very same thing happen with 357 starline brass. Only happened with new brass. Glad to see the response from Dillon.
