Question: Does the sizer die expand the mouth of the case for cast bullets?
Document: Die set works beautifully, with complete instructions for those who are new to reloading. The carbide dies keep you from having you use case lube, so it makes for a simpler, cleaner operation. I had no problem resizing 1000 .40 S&W cases as soon as I got it. These are good for 10mm cases as well.
I have the same carbide sets for my other pistol rounds. Carbide sets are much easier to use since they do not require case lube. I've always had great results using RCBS dies.
If anyone is looking for a good die to use get the carbide much less work and a lot cleaner
Haven't reloaded yet, need a new book, which I'm waiting for but I'm confident that the die set will work out fine.
Orders this die set while looking up 223 dies and thought the dies were Carbide Dies for 223 once they arrived they were 40 S&W and 10 MM die. I went back to check the add and found that no where in the add did it show the caliber the dies were for. I am sure these dies will be good for 40 SW but they are not what i ordered.
i recently purchased a set of the tungsten carbide RCBS dies for my press. these are top of the line dies, they are hand inspected twice prior to leaving the factory. they come in a nice hard shell case with slots in it to hold them in place. they also eliminate using lubricating the the brass. rcbs tungsten carbide dies are very rare and hard to find. i recommend if you see a set buy them. it took me 2 months to find my set.
I bought this to fill my 300 dollar rebate and don't even own a 40 cal yet...I DO own 6 other sets of RCBS carbide dies and can attest to their quality for the price.. I run IDPA and 3 gun competition and for progressive presses I just adapt a bullet seating adapter to the expander die and run 700-800 rounds an hour without needing a 4 die set.
Works great! they hold their positions well and the lock rings stay put. Price was okay for carbide. Wasn't Cheaper Than Dirt but wasn't Cabella's prices either. Fast shipping.
Use for my reloading, fair price, works well, cleans up easily and adjusts easily, can do one time set and load a bunch
This is my third set of RCBS carbide dies (0.44, 0.40 and 9 mm) and they work very well. I don't use any lube and don't have problems. I use them in a Hornady Lock-and-Load manual press and the whole unit works just fine.
