Just a reminder. Our S model works with 9mm, 40S&W, 45ACP and 223 Rem conversions. If you want, for example roll size 308 Win, you have to purchase L model and if you want to roll size rimmed cases like 44 Mag, you have to purchase Ultimate or HD.

This is why we use case rollers and you should too :)
1) a sizing die cant reach where a case roller can
2) some guns just damage a case rim, you can also damage the rim by stepping on the case on a shooting range
If you want 100% reliability you should roll size.
