Need Help: .308 FTF

[james_bond_007]

Hypothesis 4: A small base resize die is needed.

Experiment 4: Resize some of the "fat" cases from Experiment 1 (1) using :

• My Lee resizing Die (Pacemaker set)
• My new Redding SB FL resizer die (#91355)

And recheck with the Wilson gauge.


Results 4:

1. Most cases resized (or actually re-resized) by the LEE die will NOT chamber in the Wilson case gauge
2. All cases resized by the Redding die WILL chamber in the Wilson gauge
3. All cases that would not resize in (1) and were passed through the REDDING die WILL chamber in the Wilson gauge.

Conclusions 4:

As overall, I did not have a majority of "fat" cases, I can conclude that the Lee die is able to resize most of the brass properly; however, the cases it could NOT resize seem to have been taken care of by using the REDDING die.

My adjustment to my reloading procedure is the following:

1. Resize with the Lee die
2. Check with the Wilson gauge
3. Run all "rejects" from (2) through the Redding die
4. Recheck with the Wilson gauge
5. Discard any rejects (or rotate them and re-run through Redding die until they pass the Wilson gauge test)

I "Could" just run them all through the Redding die, but as I've read about "overworking the brass" with SB dies, if I can get them to "pass" with the LEE die, I'll only overwork the ones that really need the SB dies, and not ALL the brass.
