The RCBS 11103 is a full-length 2-die reloading set designed specifically for .223 Remington, built to handle the tight chamber tolerances common in modern semi-automatic rifles. If you're reloading for an AR or other .223 platform, this set gives you the precision tools needed to produce consistent, reliable ammunition. The two-die configuration keeps your reloading bench simple without sacrificing the control you need for match-grade or defensive loads.
The set includes a small base sizer die paired with an expander-decapping unit, which handles the critical first step of preparing fired cases. The small base design resizes cases below SAAMI minimums, bringing down the shoulder and body dimensions by a few thousandths of an inch—essential for tight-chamber .223s where standard full-length sizing can leave cases too large to chamber reliably. The integrated decapping pin removes spent primers in the same operation, saving time and keeping your workflow efficient.
The seating die comes with a built-in roll crimper that secures the bullet as it seats, locking it firmly in place during loading. If you prefer to seat without crimping—useful for certain applications or bullet designs—simply back off the die until the crimp ring disengages from the case mouth. This flexibility lets you adapt the die to your exact reloading needs without buying extra equipment.

Frequently Asked Questions
Will this .223 die set work in my tight-chamber AR?
Yes. The RCBS 11103 is designed with a small base sizer that resizes cases below SAAMI minimums, reducing shoulder and body dimensions to ensure reliable chamber fit in tight-tolerance rifles. This makes it ideal for modern semi-automatic platforms.
Can I reload without the crimp feature?
Absolutely. The seating die includes a built-in roll crimper, but you can disable it by unscrewing the die until the crimp ring no longer contacts the case mouth. This lets you seat bullets without crimping, giving you control over your final load.
What's included in this 2-die set?
The set contains two dies: a small base sizer die with an integrated expander-decapping unit, and a seating die with a built-in roll crimper and seater plug. Together they handle sizing, decapping, and seating in one efficient workflow.
Does this work for pump and lever-action .223 rifles?
Yes, the RCBS 11103 is designed for use in semi-automatic, pump, and lever-action rifles chambered in .223 Remington.
