17 Fireball from 221 Fireball

[durango]

I'm starting to acquire parts and equipment to build a 17 Fireball. I have 300 pieces of Remington brass in 221 Fireball to be necked down to 17. I'm going to buy Redding dies-neck sizer with the bushings. Questions: What size bushing is appropriate for the R-P brass and Hornady bullets? Is it necessary or advisable to use a larger bushing as a step in the necking down process? Thanks, Steve

One pass with the .221 Fireball brass thru a "full length" 17 fireball die and you're done.
Once you get the brass formed down, "then" think about a bushing die. Bushing dies to reform from 22 to 17 don't work as well as they could.

If you have a 221 full length die pull the expander plug out of it and size your brass with it before you size it into a 17 fireball die.....you will have less failures that way. I made a bunch of 17 fireball from 223 brass with a step down die last winter and found that a 221 die with no guts was a good start.

I have all the dies you'd need and probably many more. I used to form 17 Fireball from .223, but no longer own a FB. Pretty sure I can set you up for a very reasonable price.

Thanks for the replies everyone. PM to Sparky. I still need to know about the size of bushing to order for the Redding die-necked down R-P brass with Hornady bullets. (I scored 2 boxes of 25 gr A-Maxes on markdown at Scheels last night!) Steve

Best bet is to make up a "dummy round", measure the loaded neck and pick a bushing maybe .002 smaller and go from there. if you plan to neck turn, do that first then get your measurement.
