Bushing size advice
I'm reloading for 17 FB and using .223 cases prepped by a member. My question is what size bushing should I use for a Redding Neck Sizing Die?
I made two dummy rounds. One with once fired factory brass and the other with the formed 223 brass. The factory brass measures .199 at the neck and the 223 brass measures .201 to .202. I also have new factory ammo and the neck measures .198. Both dummy rounds chambers fine. Thanks. Bill |

I normally start with bushing .002" smaller than the neck diameter with a bullet seated.

I'm using a .199 for fired Remington brass. Generally speaking the Redding stamped bushings size sometimes doesn't match what comes out of the die.

What is your chamber neck dia. those .202 could be getting snug. I'm with Aaron I go with .002 less than a loaded round also.

I usually get two bushings, 1 at .001 smaller than loaded, 1 at .002. Never used Redding bushings, only Wilson, but I've heard the Reddings can run on the small side.
How are you planning on FLSizing? A Redding FLS bushing die is a good way to go. |

My once fired factory cases measure .206. I use Redding FL sizing die but it's not the one that is the bushing die.
The dummy round with the formed 223 cases measure .201-.202 loaded diameter and it chambers easily. So I'm thinking a .199 bushing would work for these cases and either a .197 or .198 bushing for the factory cases since the dummy round for that case measured .199 loaded diameter? Thanks for all the help. |

If it were me, I would get a .199 and a .200 Bushing, to have the bases covered.
I have been researching the Pros & Cons of Bushing Dies, and Redding is currently recommending bushing sizing at 0.100 under the average neck diameter measurement of a loaded/seated bullet cartridge, to prevent excess neck/bullet tension. They must have had issues with the 0.200 Recommendation. Bill

Two suggestions I have.
Take some loaded rounds and use your fingers to try turning or pulling the bullets out. IF you can, it's not small enough. Make a chamber casting and measure the results then you'll know for sure what you have and can get what you need then. I bought a reamer from a member for the .17VR that had a .195" neck. When I fired a dozen or more the shoulders split. Wasn't any room for the necks to expand. Ended up having the chamber neck reamed out to .203", never had a problem since.
