Making 20 vt brass
I have a Redding two die set, fl sizer and micrometer seating die. I have made 20vt brass by necking down Rem 221 fb.
For some reason I can’t figure out how I did that in the past. Today I ran some 221 brass in to the fl die and ended up with a neck that’s partially sized to 20 cal, but the bottom third of the neck is not sized and the rounds won’t chamber. I have only ever had this set of 20 vt dies and can’t figure out how I formed 20vt brass. Help please. |

Simple
Set the die so that at full stroke, the shell holder is tight against the forming die.

take the fl die and run it down till you've have a .204" neck.

20vt brass
I figured it out
The sizing die is a bushing die I did not have the decapping rod screwed down all the way. It holds the bushing down So the bushing was allowed to float up 1/8” or so when the case was fully up in the die. That left a little bit of the neck not reduced to 20 cal. I screwed down the priming rod, problem solved. Thanks for the responses |

Necking down, using a bushing die, you won't get 100% of the neck sized, there's always a small portion of the neck that doesn't get sized down.

Making 20 VT brass
Will be interesting to see what others have found, I tried leaving some clearance and then held in place. I found that I had better results with the formed and then fire formed brass with no clearance, but with the bushing held down. So I guess I am asking for thoughts or a poll of loose or tight on the bushing.. Bill K

I always leave a little float in the bushing.

I screw it down until there is contact with the bushing, then back it off the least amount possible. Basically, I want the bushing to be able to center itself while sizing as much of the neck as possible.
As far as the bushings themselves.... I was happy with both the plain and coated Redding bushings. Gave the bushings from Custom Reloading Tools (CRT) a try and now use them exclusively. My seat-of-the-pants opinion is that the transition from die to bushing has a better feel when forming brass. |
