1200B Case Trimmer

Does the 1200B case trimmer chamfer the case mouth as well a trim to length, or is it necessary to perform that step seperately?

Thanks

The RT-1200 does an outside chamfer and deburr. It does not do anything to the inside.

I am loading 223. I recently set-up a 650XL tool head with the size/decap die in station 1 and the 1200 trim die in station 4. I thought I could kill two birds with one stone. I noticed that the 1200 trim die reduces the case neck even smaller than the size/decap die. It will reduce the OD from .248 down to .242.

I experience a lot of bullet damage when seating the bullets. It makes a distinct ring around the bullet from the force required to seat the bullet. If I use only the trim die I will have a deformed case. Even after resizing the case in the size/decap die again it is still noticeable.

That being said what is the best way to trim cases? Below is the best method I have used so far to eliminate the bullet damage.

For Example:

1. size/decap in seperate tooling head

2. trim afterwards using the same tooling head.

3. Resize case again in station 1 during the loading process.

or am I doing something wrong? This is now the third time I've used the trimmer and becoming a little frustrated.

Please hep.
