9 mm resistance in resizing die (RCBS carbide)

[Longhorn 76]

I just wonder if he really has a carbide die or not.

Maybe he is mistaken, and really has one of the steel dies.

I have a newer 9mm carbide die and have the same issue. I just hit them with some one shot and keep on truckin.

Aside from making it easier when you have some case lube applied, the press tends to run smoother which means less powder clean-up, timing, etc.

40 years of reloading and I lube pistol cases - particularly 9mm - I use a RCBS press or a Dillon. Put a little lube in a plastic bag - dump cases in shake them then load them. I load 1000 a month and every bit of help is welcome.

I use a Dillon SDB with Carbide dies.

For 9mm brass I normally wash clean and tumble with polishing media and have no problem. If I run a washed brass before tumbling then I can feel some resistance. I also noticed as others have stated, that different head stamps have different resistance based on case thickness.

For .45LC especially new brass, I use Hornady One Shot, just spray let dry and size. No cleanup or after tumbling required.

Don’t forget to clean your dies also, if you get something on it, it will transfer to what you feel resizing. Just my two cents worth.

If all else fails, ask for a new set of dies.:banghead:

Tapered cases are always harder to size in carbide dies. Look at the .30 carbine, it's always been a bear to resize, especially when you consider how small it is.

Dillon makes carbide sizers for .223 and .308 but they specifically state that lube MUST be used with these dies.

If you're having a tough time sizing, a little case lube certainly won't hurt anything as long as it's removed so that it can't contaminate primers or increase case head thrust when the round is fired.

Another trick that may help is polishing the cases for a couple of hours with Nu Finish car polish, really clean cases with a little wax or polymer on them seem to run more smoothly through a low friction die.

I use Lee dies (carbide, too) and noticed it takes less force to resize if I use some lube. I mix 1 part Lee lube with 10 alcohol as indicated in the manual.

I use the same die and no lube, not a problem or whimper. Any water on the case will cause major problems. Now small base sizing MG fired 7.62 does take a lot of lube.

I use Lee carbide dies for 9m/m and lube the brass. Much easier for an old shooter like me.
