Making 17/223 cases ?

[Yotecallr]

I'm buying a set of Hornady dies in 17/223 for a BHW barrel I'm getting. How do I form a 17/223 case from 223 brass ? Thanks

Nearly 40 years ago I had a H&R Ultra Wildcat in .17/223, way before I worried or even knew about throat erosion and a lot of other things, it was one of my favorite rifles at the time and I still think about getting another one.

It was an easy wildcat to reload for, just run a .223 into the .17/223 full length sizing die and done. I do not recall weather on not trimming to length was needed and never even thought about the neck diameter. On a custom rifle with a possibly tight chamber neck checking the neck clearance would certainly be wise.

Good luck,

John

If you want to make sure you don`t lose any brass, run it through your seating die before your sizing die. That takes it down in 2 steps instead of 1.
