How far down the case do you run the sizing die for revolver cases? I generally go as deep as the bullet I'm using. Just wondering if I was doing it right.
I think these instructions are just for bottleneck rifle cases!All the way down as far as the die / shellplate will let me. Just follow the die mfg instructions for setup. Most tell you to raise the ram and screw in the die till it touches the shellholder/plate, lower the ram and add another 1/8 turn to allow for cam over then raise the ram again and lock the die ring in place.
The reason I ask is I'm quoting the RCBS Instructions from a set of carbide dies "the die should be adjusted to size only the portion of the cases that was expanded while being fired. Never try to sized the full length of the case as a small ring may appear, which is undesirable, and could weaken the case. "I run the die down until it touches the shell plate with the ram fully raised then tighten the lock ring. To the best of my knowledge all cartridges intended for revolvers are straight walled and head space on their rims. For those pistol rounds intended for auto loaders they head space on the mouths of the case. There are bottle neck handgun cartridges, not sure what they head space on, at any rate “ full length resize” means full length or as far as the case will extend into the die.
Unless they are very old dies all pistol sizing dies I’ve ever owned have a carbide ring that does the resizing. One would have to lube the cases otherwise.
For revolvers, I size all the way down to the shell holder/shell plateHow far down the case do you run the sizing die for revolver cases?
The thing is that the whole case expands all the way down to the web...so you'll need to resize the case as far as you are ableThe reason I ask is I'm quoting the RCBS Instructions from a set of carbide dies "the die should be adjusted to size only the portion of the cases that was expanded while being fired.
This is the route I chose to use for optimal resizing while also obtaining sufficient neck tension...I found it, in addition to using a M-die profile Expander...to be the most efficient processAnother solution is to use a Redding Dual Ring Carbide Sizing Die that sizes the body down just enough to allow the brass to drop easily into the chamber, while sizing the neck for sufficient tension on the bullet.
So that’s s where that dad burn ring comes from in my 357 casesThe reason I ask is I'm quoting the RCBS Instructions from a set of carbide dies "the die should be adjusted to size only the portion of the cases that was expanded while being fired.

Not with carbide dies.
Get a Marlin 1894 in 45Colt Dave and you will quickly realize that if you don't partial resize with a carbide die, you will have head separations after 2 or 3 loadings. The chambers are huge and partial sizing increases brass life dramatically.
