Shoulder bumping technique

ALL companies make their shell holders to the accepted standard of 0.125"... if you have one that is not, return it to the maker for a replacement.
Yeah and it will cost you atleast 8.95 for shipping, just put it in the die box for that die alone and it's a done deal.
Just like all saami reamers are ground to the exact same specs.
 
The easy way to consistently bump your shoulder to a repeatable -.002" ( or where your case seats fully in your rifles chamber and easily extracts) is by adding 2 items from Redding to your inventory.
You no longer will need to constantly adjust your full length resizing die.
rather set it once and forget it.
If this sounds like it's right up your alley then please read on.!
You will need two items as stated before.
1) Redding Body Die (caliber specific)
2) Redding Competition Shell Holder Set (again caliber specific )

Place your Redding Competition Shell holder marked .010" on your reloading press while lowering the handle until a firm contact has been made.
Now clear your ram while screwing in your body die another 1/16 - 1/8" to allow for a camming action, and lock in place.
Now with your trusty rifle by your side proceed as follows.
Place a lubricated cartridge case onto your press and simply lower your ram.
You are not FL Resizing but only making contact with your cases shoulder.
Note that the shell holders are designated as follows .010" - .002.
Remove case from press and place in your rifles chamber.
If it doses not feel correct whether feeding or extracting well then remove your case and add the next lower shell holder.
Repeat the procedure until your rifles action will close and open with just the right amount of pressure.
(I find that somewhere between .006" - .004"shell holders work the best for most of my rifles)
Please note that your actual shell holder will vary until you find the right one.
Once you have found the correct shell holder size you are all set.
Now any time you need to bump your shoulder after using your FL resizing die you no longer need to screw your die in or out wasting your valuable time.
It is another operation but once set up will never vary .

Simple use of a body die and shell holder set by Redding will make your reloading process much more productive.
The body die is very reasonably priced, however the competition shell holder set, because it's a set costs a little more.

I hope this helps, as I use these religiously in multiple calibers ,and rifles.
Now here are two plus factors for buying into the Redding Body Die, and Competition Shell Holder Set.

First if you shoot several rifles in the same caliber all you need to do after FL resizing is simply change shell holders while using the body die to establish the correct shoulder bump for each rifle.(document everything for further reference)
Secondly if you shoot more than one caliber with the same parent base design you do not need to buy a caliber specific shell holder set as the shell holders will work.
Example: Redding Competition Shell Set holder size#1 will fit 22 -250, 243, 6.5 C, 270, 308, & 30 -06 as well as many other wildcat calibers. (so you will be getting your moneys worth)

Belted cases unfortunately are a different story. (Caliber Specific - some will fit multiple calibers)
Just my 2 Cents worth !
 
Can I use the Redding Competition Shell Holder Set with my rcbs resizing die or do I need the Redding body die
 
Yeah and it will cost you atleast 8.95 for shipping, just put it in the die box for that die alone and it's a done deal.
Just like all saami reamers are ground to the exact same specs.

No... all SAAMI reamers are not ground to the "exact same specs", because SAMMI specs allow a lot of variation in reamer size and chamber size - usually about 10 thou. and still be inside of spec.

I have been hand loading since the late '50's and was at one time, I was the largest RCBS dealer/wholesaler of RCBS loading equipment, east of the Mississippi. I also owned an ammunition remanufacturing company from 2008 to 2014, where we made ammunition for companies like Stag Arms.

I have never seen a shell holder more than 0.0005" off of the 0.125 standard.
