I am interested in buying RCBS X dies for .308 and .223. My son and I shoot various models of the same caliber Rock river/ Saiga / Colt, etc. and I wonder if I should get small base dies just to avoid potential chambering problems.
Just getting started in the large volume reloading thing so any advice would be appreciated
Thanks

You shouldn't need small base, even for an autoloader ... they do work the brass, and thereby shorten its life, more than a regular FL die.

For information about the X-die try:

I have one and it works as advertised. Mine is a small base as well. Also about small base. You will find several different opinions about whether they are needed or not. I tried to search and find a thread I remembered with good discussion but the search feature is down right now.

The truth is they do work the brass more than a regular FL die thus shortening the life. They are useful for tight chambered autoloaders and/or oversize machine-gun brass. However, do you need one? Only experimenting with your brass and rifle will tell. Most can probably get away with FL only.

I kinda wish I had tried a FL before I bought my small base. My Fal eats everything.

Most auto-loaders will eat anything. The common Small Base warning is another example of "conventional wisdom" being B.S. more often than not.

Instruction for the X die. http://www.rcbs.com/downloads/instructions/XDieProductInstructions.pdf The small base is not needed.IMO But heres what RCBS thinks on the subject. Q. I see a Small Base Die Set listed for my caliber. Do I need these or should I buy a Full Length Die Set or Neck Die Set? How does each set differ?

A. The Small Base Die set is intended for use for ammunition to be used in auto, semi-auto, and lever action rifles so that the loaded round chambers and extracts easily. The Small Base Sizer Die sizes the case from the shoulder to the head of the case a couple of thousandths smaller than a Full Length Sizer Die. In certain calibers it also sets the shoulder of the case back a thousandth or two more than the Full Length Sizer Die. The Full Length Die Set or Neck Die Set is not normally recommended for ammo to be used in auto, semi-auto, or lever action rifles. The Full Length Die set is recommended for ammunition used in bolt action rifles, particularly for ammunition to be used for hunting. The Neck Die Set can also be used to produce ammunition for use in bolt action rifles. The Neck Sizer Die sizes only the neck of the case so it will hold the bullet firmly. It does not size the body of the case nor does it set the shoulder back. Neck sized cases will usually chamber for three or more firings, depending on the powder charge and chamber dimensions. However, over a period of time, a slight drag will be noticed when the bolt is locked. At this point, cases will need to be full length sized and the shoulder set back so they will chamber and extract easily.

Reguler based X-dies for my M1 Garand and Bushmaster. Thousands of rounds reloaded for each.
