RCBS X Die Small Base Sizer .223 Rem
Revolutionary reloading die that eliminates repetitive case trimming. Specially designed mandrel with expander ball and decapping pin reduces case mouth growth during sizing, allowing cases to stabilize below maximum length.
The End of Repetitive Case Trimming
The RCBS X Die Small Base Sizer represents a significant advancement in reloading efficiency. This patented design solves one of the most tedious aspects of handloading: the need to trim cases after every few loadings.
How It Works
The X Die features a specially engineered mandrel with an integrated expander ball and decapping pin. Rather than shortening case length, the mandrel's extremely close tolerance to the die neck wall prevents the neck from thickening during sizing. This critical design feature stops the case mouth growth that normally forces repeated trimming.
Real-World Performance
- Initial trim required: One trim of .020 inch off maximum length to standardize your cases
- After that: Cases stabilize below maximum length with no further trimming needed
- Case growth: Initial growth of a few thousandths of an inch, then stabilization
- Accuracy: No discernable loss of accuracy or case life
What You Need to Know
